tied to the specimen. The fauna of Sattelberg is particu- 

 larly interesting, because it is to be regarded as most typical 

 for the interior of German New Guinea, and from that place 

 the best specimens of the collection have been obtained.

Description. — Head large; snout longer than the orbit, the 

 diameter of which is nearly equal to its distance from the 

 nostril, but a little shorter than its distance from the ear- 

 opening ; forehead concave, loreal region also concave, espe- 

 cially anteriorly ; ear-opening roundish, about one third of 

 the eye. Body and limbs rather elongate. Digits somewhat 

 depressed at the base, strongly compressed distally. Head 

 granular, with small tubercles on the temporal, occipital, and 

 posterior part of parietal regions. Rostral subquadrangular, 

 its height being about three fourths of its breadth, with a 

 deep median cleft above ; a large supranasal, separated from 

 its fellow by a small azygous shield ; nostril pierced between 

 the rostral, the supranasal, the first upper labial, and three or 

 four small granules ; twelve upper and ten to twelve lower 

 labials; symphysial triangular; two pairs of chin-shields, 

 median largest and forming a long suture behind the sym- 

 physial; throat granular. Upper surface of arm above the 

 elbow covered by subimbricate scale-like granules; with 

 this exception, body and limbs covered above with small 

 granules intermixed with small, round, feebly keeled tubercles ; 

 scales covering a fold extending on each side of the body, 

 from axilla to groin, enlarged to similar tubercles. Ventral 

 region covered by scales, larger and more imbricate towards 

 the middle of the body, where their diameter is considerably 

 greater than that of the dorsal tubercles. Male with a long 

 uninterrupted series of femoral and prseanal pores, about 30 

 on each side, forming aright angle in the middle, but (unlike 

 the condition in G. Lorice) this series is not preceded by any 

 additional prseanal pores. A distinct prseanal groove. Tail 

 cylindrical, tapering, covered by a heterogeneous lepidosis. 

 The proximal third bears the same kind of tubercles as on 

 the back, but the granules between them are larger, scale-like, 

 and subimbricate. Distally the tubercles disappear and the
