AND FROGS FROM SINGAPORE.

The colour of the back is uniformly brown, there beiug no trace of 
tbe longitudinal pale bands usually found in this form ; the pree> 
frontal is wanting ; tbe two postfrontala are slightly unequal and 
divided by a curved line ; they are in contact with the supranasal : 
this is probably an individual peculiarity. Tlsere are also but 22 
series of scales round tbe body instead of 24 ; about 3*1 occur in a 
longitudinal line between tlie axils of the fore and hind legs as in 
the type ; and in other respects tbe specimen agrees with Chinese 
examples. 
I am by no means sure tbat this form and its allies are really con- 
generic with E. pavmenlalusy the type of the genus Eumeces. (See 
Peters, Monatabericht Akad. Berl. ISG-J, p. 48 ; Stoliczka, J. A.S. B, 
1870, ixxix. pt. 2, p. 17-4, ai^d 1H72, xli. pt. 2, p. 121 ; Anderson, 
P. A. S. B. 1871, xL p. 1 81.) All these Scinks are very puzzling; 
and the generic distinctions accepted, such as the difterences between 
smooth and keeled scales, transparent or scaly eyeUd, presence or 
absence of supranasal shields, arc scarcely of generic importance, and 
are merely convenient guides to identification. 
Cylindrophis LiNEATtrs, sp, nov. (Plate XX.) 
Head depressed, broad, short, the width between the eyes being 
equal to the length from the eye to the tip of the snout. Each 
frontal is as broad as long. The vertical is longer than broad, sub- 
trapezoidal, the anterior margins meeting nearly at a right angle, 
the posterior termination slightly rounded. Supraorbitals longer 
than broad, each nearly equal in size to the vertical. Oecipitals 
more than Imlf as large as the verticah Postocular very small, 
scarcely half the size of the first labial. Scales round the middle of 
the body in 21 rows. Ventrals, where widest, in the middle of the 
body, nearly twice the breadtli of tbe scales ou the sides ; but the 
rows on each side of the ventrals are rather broader than the lateral 
and dorsal scales. Ventrals (from chin-shields to anaP) 215, two 
anals, subcaitdals 9 besides the terminal scale. 
Jiack longiiudinallif banded. A blackish -brown stripe, three scales 
wide, runs down the middle of the hack from head to tail, and is 
bordered on each side by a narrower white baud ; below this again 
is a second, broad, blackish hand of irregular width, witli the lower 
border waved. This longiludiiial hand is BfpAratfd by a narrow 
wavy white stripe from the transverse dark hands of the belly ; the 
latter are wider than the alternating white hands ; and, as in other 
species of the genus, the bands on the opposite sides of the abdomen 
do not precisely coincide. Head and tail yellowish white, with a 
few blackish spots. 
Only a single specimen is sent This measures 35 inches, of whicU 
the tavl is t>-7;> in. The Snake is probably rare.
