34. Ltgosoma wollastoni, sp. n. (PL XXX. fig. 1.) 



Section Lygosoma. Body elongate, limbs short; the distance between the end of 

 the snout and the fore limb is contained once and two-thirds in the distance between 

 axilla and groin. Head small, much flattened ; snout moderate, obtusely acuminate. 

 Lower eyelid scaly. Nostril pierced in a single nasal ; no supranasal ; rostral 

 narrowed and produced posteriorly between the nasals, forming a suture with the 

 frontonasal, which is a little broader than long ; praefrontals rather small and 

 narrowly separated from each other; frontal a little longer than broad, broader than 

 the supraocular region, as large as frontoparietals and interparietal together, in contact 

 with the first supraciliary and the first supraocular and a small portion of the second ; 

 four supraoculars ; seven or eight supraciliaries ; frontoparietals and interparietal 

 distinct, subequal ; parietals forming a suture behind the interparietal ; a pair of 

 feebly enlarged nuchals ; fifth and sixth labials below the eye. Ear-opening oval, a 

 little smaller than the eye-opening ; no auricular lobules. 32 smooth scales round the 

 middle of the body, the two vertebral series transversely enlarged. A pair of enlarged 

 pr<Eanals. Limbs widely separated when pressed against the body. Digits short, 

 feebly compressed ; 17 lamellse under the fourth toe. Tail thick. Dark brown above, 

 sides with lighter ftiottling ; lower parts yellowish white, this colour extending to the 

 last two upper labials.

A single specimen from the Mimika R. (B. O. U. Exped.). 



Closely allied to L. muelleri Schleg. and especially L. pratti Blgr. (T. Z. S. 1903, ii. 

 p. 128, pi. xiii. fig. 1), diifering from the latter in the number of scales round the 

 body (32 instead of 36) and of lamellar scales under the fourth toe (17 instead of 13 

 or 14). L. lorice Blgr. (Ann. Mus. Genova, [2] xviii. 1898, p. 698, pi. vii. fig. 1) is 

 also related, difiering in the narrower frontal, in contact with nearly the whole inner 

 border of the second supraocular, in the narrower suture between the rostral and the 

 frontonasal, and in the less fiattened head. As I have previously pointed out 

 (P. Z. S. 1903, ii. p. 128), L, lorice connects the sections Ilinulia and Lycjosovia. 

 Another species connecting these two sections is L.jeudii, nom.-n. [L. tigrina Lidth de 

 Jeude, Notes Leyd. Mus. xviii. 1897, p. 250, pi. vi. fig. 1, non De Vis).
