squamiceps, as figured by Gray (plate 8, fig. 3). The first frontal 

 plate, which is whole in the figure, is divided in two in my 

 specimen. The body of the latter is much wider than the head, 

 increasing gradually in width till within a short distance from 

 the base of the tail. The tail is somewhat abruptly joined to 

 the body, and is almost as long as it. The body of Pygopus 

 squamiceps is scarcely half as long as that of my example, but 

 is thicker in proportion. The only markings are some minute 

 black dots along the sides of the body, while my specimen 

 presents five conspicuous black marks on the posterior part of 

 the head. The largest one is on the middle line of the body, 

 oblong, with an anterior stalk-like projection ; on each side, 

 but farther forward, is a smaller but similar spot, the "stalk" 

 pointing to the upper angle of the eye ; in a line with them are 

 two others, but bar-like, one on each side, commencing opposite 

 the hindmost extremity of the central spot and extending 

 diagonally backwards and upwards. The length of the central 

 spot and these bars is about one-fourth of an inch ; that of 

 anterior ones one-eigthth of an inch. I cannot discern any 

 dark spots along the sides of the body, but they are distinctly 

 visible from the base to near the tip of the tail at irregular 

 distances, and bordered with white on the lower side. The last 

 inch or so of the tail is covered with very much smaller scales, 

 which are of a yellowish-grey tint, and are marked with short 

 longitudinal lines. The tip of the tail is very thin for about 

 three- sixteenths of an inch, and not hard. The general color 

 is a clear ashy grey above and light grey, tinged with pink, 

 below. 



8hould this specimen prove to be new, the name Pygo'pus 

 longicaudatiis might be suggested as appropriate. 



Several examples of Fygopus squamiceps have been brought 

 to me that were captured under rocks on the hillsides about 

 Ardrossan, Torke's Peninsula.
