fourth toe a little longer than the third. There are three pairs of 
preeanal scales, subequal in size; subcaudal scales not enlarged. 
The upper parts are brown, many scales having a whitish or 
blackish dot ; the blackish dots are predominant on the sides, where 
they are arranged in longitudinal series. Lower parts whitish.

SNAKES. 
CoRONELLA NoTOTENIA. (Pl. XXVI. fig. 1.) 
Vertical shield elongate, nearly twice as long as broad, much 
longer than the two frontals together, and as long as the occipital, 
which is rounded behind. Rostral just reaching the upper surface 
of the head ; loreal square ; anteocular single, large, extending to 
the upper surface of the head, but not reaching the vertical ; two 
postoculars. Eight upper labials, the fourth and fifth entering the 
orbits, the last small; temporals scale-like, 14+2+3, the anterior 
the largest and in contact with both postoculars. Two pairs of chin- 
shields ; the posterior are rather longer than the anterior, and pointed 
behind ; there are four lower labials in contact with the front chin- 
shields. Scales in seventeen rows, with a single apical groove. 
Ventrals 177 ; anal bifid; subcaudals 76. Posterior maxillary tooth 
grooved. 
Greyish brown: a deep brown band commences on the crown of 
the head, it being darkest and serrated on the anterior part of the 
body ; it becomes fainter posteriorly, and is accompanied by a series 
of black dots on each side, which disappear on the tail. A brown 
line runs along the third outer series of scales, from the middle of the 
length of the body to the extremity of the tail; belly brownish 
yellow, marbled with brown. 
Total length 143 inches, the cleft of the mouth measuring 4 lines, 
and the tail 34 inches. : 
I take this opportunity of substituting the name of Crypsidomus 
for that of Rhamnophis, which I had given to a genus of West- 
African Snakes (Ann. & Mag. Nat. Hist. 1862, p. 129), but which 
is preoceupied by a genus of East-African Ophidians described by 
Peters.
