concretion were disseminated through the whole substance of all the 

 lower and lateral muscles of the thorax and of the abdomen. 



After having finished my notes on the anatomy of Monitor nilo- 

 ticus, I received from the Society's Menagerie a specimen of a third 

 species, Regenia alhogxdaris, which had died there shortly after its 

 arrival from Port Natal. It proved to be a female, and was 40 inches 

 long, and 1 1 in. its greatest circumference. It was in a very emaciated 

 state, and had died from an extensive disease of the intestinal tract, 

 the upper portion of the jejunum and the entire ilium being covered 

 with ulcerations, and with hardened purulent exudations. The 

 fatty masses observed in the two other species were present, but 

 shrunk to a thin layer of fat. The two genera Regenia and Monitor 

 being closely allied, the present species does not differ from what I 

 have previously noted in any of the principal points, more resembling 

 R. ocellata in some minor respects, and in others M. niloticus. It 

 has the black pharynx, the curved stomach, the nine-lobed kidneys, 

 the uterine sac of the former; whilst the form of the sublingual and 

 submaxillary glands, and that of the liver with the gall-bladder, are 

 exactly the same as in M. niloticus. I have, however, been able to 

 ascertain some other points, by giving which my notes on these highly 

 organized Saurians vrill be rendered more complete. 



1 , There is a collection of glandules along the outer side of the 

 mandibulary bone, forming a sublabial salivary gland ; the fluid is 

 emptied by a series of numerous small foramina between the lip and 

 the jaw. 



^ 2. The ovarium is narrow, elongate, equally developed on both 

 sides ; it contained eggs from the size of a pea to that of the head 

 of a pin (in March). 



3. The uterine sac on the dorsal side of the rectum, which I 

 have described in R. ocellata, is equally developed in this species, 

 and divided superiorly into two short horns, one for the ostium of 

 each of the oviducts ; the ostia were wide enough for a tubulus of 

 2 lines diameter. 



4. The clitorides are double, similar to the penis, and each of them 

 terminates in two small cartilaginous processes.

In the present paper I propose to give a list of the Snakes in the 

 province of Bahia, which I have been able to collect during the last 

 two years, enumerating them in the order in which they occur in the 

 Catalogues of the British Museum, and adding such remarks as I 

 may be enabled to make.
