Thought to be endemic to Wyoming and known from only a few locations, this species is actually not uncommon in parts of southern Alberta. Some old collections (1960s) from Alberta and Saskatchewan misidentified this species as B. paludosa. Identification confirmed by D.C. Rogers.

Image 1 shows male.
Image 2 shows male. The twist in the distal portions of the second antennae can be seen.
Image 3 shows a medial view of the male's right second antenna. The medial-anterior twist can be seen.
Image 4 shows a ventral view of the left male gonopod. The two denticulate mounds of the everted penis can be seen.
Image 5 shows the female with elongate ovisac.
Image 6 shows the female with dorsolateral sub-conical bosses on thoracic segments 3-7 (a serendipitous effect of the lighting: these are normally hard to see).
For comparison, image 7 shows the heads of male B. paludosa and B. serrata, the latter having been identified as the former in some older collections. The very small accessory branches of paludosa's second antennae can be seen on the medial surfaces where the distal segments emerge (these are absent on serrata).

Single vine (the original (type) specimen) growing on Kunzea triregensis. At the time this observation was made the vine was being shaded out and was in danger of dying out. Our (Department of Conservation) 1991 field work involved careful pruning of the canopy to let in more light and tying up (on to cables) of the vines that were found trailing in the dense vegetation. As a result of these measures the vine flowered for the first time (since it was discovered in 1946) in 1995. However, seed set in the wild is still not happening, probably because the flowers are destroyed by kakariki (Cyanoramphus novaezelandiae novaezelandiae)

As my 1000th observation submitted to iNaturalist, here is something a little different and unusual from my archives.

My colleagues and I took this photograph of an actual original and unique X-Ray (physical "hard copy") film made in the Emergency Room of the University hospital in which I worked night shifts back in 2002. It was the regional center for medical treatment of snake bites in north central Florida.

This snake had bitten someone late at night, roughly in the vicinity of Cross Creek, southeast of Gainesville, as I remember, and the snake was killed and brought to the E.R. as proof of the species of poisonous snake that had inflicted the bite, for antivenom administration purposes. There were a couple different types of antivenom then, and they usually took a little time to reconstitute or prepare. All pit vipers in Florida inject similar venom when they bite, but it is different from that of the Coral Snake for instance, which is North America's only native Cobra. Having the actual body of the snake delivered to the E.R. is not absolutely necessary of course, but it does insure correct identification as to species, for whatever that may be worth, at the time, and in later analysis.

While identifying a snake from an X-Ray photograph may be a little unusual, it is not so difficult in this case as some might imagine. After all, here is a very large Pit Viper, totally without tail rattles, in Alachua County Florida.

Just how big was it? Coiled up as you see, it almost doesn't fit on a piece of film that was 11 by 14 inches in size. The snake's head, distorted a bit by the trauma of its demise, alone is nearly 3 inches long, measured directly on the film itself. The snake's coiled body, head to tail, can be measured on the original film by laying a piece of string on the image, tracing the course of the backbone. At 58 inches, or 4 feet 10 inches (147 centimeters) then, this a pretty large snake as Water Moccasins go.

What's more, one of the reasons we X-rayed it at all was that it had clearly recently eaten something. It had a large bulge in it's stomach, down about a third of it's body length, just past its air-filled lungs that are visible on the film as well defined darker shapes. We found the bulge was a big fish with a large blunt bony head, very visible swim bladder, which we took to be a catfish, though we lacked an Ichthyologist amongst the E.R. staff of course. I can follow the fish's spine for quite a ways in the image, but lose it somewhere along the snake's lung in the extreme right of the picture. We did not, in any case dissect the snake in the E.R. Nor did we weigh it, unfortunately. For all I know, the patient, who survived with the help of our treatment, took the dead snake and its last meal home with him when he was discharged.

The Technician that made the actual exposure for us on film, at my request, wrote the details of the exposure for future reference on the film itself, which, though the film suffered damage when it was stolen from my vehicle inside a locked briefcase and dumped out in a back alley and further mistreated both by the thieves and the weather, I can still read most of what he wrote with a "magic marker":
"40(or 46) MA
1 MAS
56 KV"
Are there any X-Ray Tech's out there who can confirm that that is in fact a good exposure for a big dead snake?

I'm pretty sure these are red hake though I might be incorrect. It's hard to see where the mouth terminates relative to eye, but the pelvic fin ray seems to terminate a little after anterior start of anal fin. Mottled brownish (with dive lights). These were schooling by the thousands at the Patriot shipwreck ≈30m depth. A couple sculpin in the mix too.

Stunning scenery on top of the plateau of "BFW" dive site. I haven't observed Isodictya in the area since Doris pseudoargus got established. Prior to that, this was a common sight on offshore ledges in northern MA.

Edge of a bog with no dung in sight (but clumps emerging from a sort of empty spot where a pile of scat likely once sat and humified). With regular, multicellular leaves (differentiating this species from S. pennsylvanicum)
