Description of a new species of the genus THELYPHONTJS. 

 BY HORATIO C. WOOD, JR. 



T. s timps onii . Cephalo-thorax closely resembling that of T. gigan- 

 teus. Cheliceres strongly curved. Their superior surface roughened by mi- 

 nute tubercles or granulations, the inner, pilose. The first or basal joint very 

 wide above, armed on its inner superior margin with five irregularly radiating 

 spines, the posterior three of which are quite small, and the third some- 

 what longer than the other two ; the fourth is rather larger, its length being 

 about twice that of the third, the fifth is shorter than the fourth, but is next 

 to it in size. The space between the fourth and fifth is greater than the inter- 

 vals between the others. The inferior inner margin armed with two small spines. 

 Second joint provided with a very minute spine on its superior, and a larger 

 one on its inferior inner margin. The third joint has on its superior inner 

 margin two minute spines and a long robust finger, bifid at its extremity and 

 strongly terrate on its anterior edge. The superior inner margin of the fourth 

 joint and both margins of its finger strongly serrate. Abdomen very similar 

 to that of T. g i g a n t e u s, but the first joint has on its lower surface a deep 

 median semicircular depression, with a much smaller one on each side. 



We have seen but a single specimen brought from Japan by Dr. Stimpson 

 of the North Pacific Exploring Expedition. 



Length of body one inch and a half, of cheliceres three quarters of an inch. 



On the Reptilia of Sombrero and Bermuda. 

 BY E. D. COPE. 



The only terrestrial animal inhabitants of the island of Sombrero, are stated* 

 to be a centipede and a lizard. The former is the Scolopendra torquataof 

 Wood ; the latter I propose now first entering upon the zoological record. 



Ameiva c o r v i n a Cope. Teeth in young and half grown specimens bicus- 

 pid posteriorly, occasionally a third cusp ; in adults a few of the posterior 

 inaxillaries and mandibulars bicuspidate, the smaller cusp antero-internal. 

 Number 20. 5-5. 20 ; 21. 21. Head and in particular the muzzle, narrow, elon- 

 gate, slightly decurved. No-tril in internasal, or nasal suture. The former 

 plates slightly in contact medially. Fronto-nasal longer than broad ; prefrontals 

 ditto, extensively in contact medially. Four supra-oculars, posterior very 

 small, the suture between second and third continuous with the posterior line 

 of the frontal plate. The latter is hexagonal, a little longer than broad ; pre- 

 sents a sub-rectangle anteriorly, and an obtuse angle posteriorly. Two fronto- 

 occipitals, longer than broad, usually in contact, forming with the two occipi- 

 tals on each side a series curving outwards, separated by granulations from 

 the supra-ocular series. Interoccipital irregular, sometimes divided. Numer- 

 ous small irregular plates upon the occiput. Rostral a little prolonged upon 

 each labial suture. Superior labials six, inferior five, in contact posteriorly with 

 two oval plates. Symphyseal and mental each broader than long ; infralabials 

 five, anterior pair extensively in contact, the posterior separated by granulations 

 from labials. Gular scales small, smooth, hexagonal ; those of the posterior 

 gular fold larger than those of the anterior. Ventral plates in twelve or four- 

 teen series, those of the external, small, rounded. Anus bordered with gran- 

 ules : anal plates four, large, arranged as part of a quincunx pattern, surrounded 

 by several smaller shields. One row of large transverse anterior femoral plates, 

 and four series of subhexagonal plates posterior and inferior to it. Exterior sub-
