382 Mr. Newport on the Class Myriapoda, Order Chilopoda. 



It inhabits the Mysore. (In the cabinet of the Rev. F. W. Hope.) 



The narrowness of the legs, with the free elevated margins of the joints, 

 and the number of the teeth, induce me to regard this as distinct.

Cephalic segment cordate, small, smooth and flattened; basilar segment large, a little nar- 

 rowed posteriorly; mandibles and tooth large; labium smooth, slightly depressed, 

 sutures absent; dental plates short, transverse and thickened; teeth eight, small, ob- 

 tuse; posterior segment of the body with a very distinct median dorsal ridge, as in 

 S. morsitans. Posterior pair of legs slightly elongated ; femoral and tibial joints equal ; 

 superior surface of the femoral joint flat, smooth, with the external margin subacute; 

 internal margin compressed, with six teeth arranged in two alternating series; two in 

 the superior and four in the inferior series, the fourth or angular one large, obtuse, and 

 slightly bifid. Internal surface flattened, toothless ; inferior surface rounded, with nine 

 spines arranged in three longitudinal series, three in each series, those of the external 

 and internal series parallel with each other; second joint flattened, with the margins 

 elevated. Lateral anal appendages short, with the apex produced, simple, or slightly 

 bind. Preanal scale four-sided, somewhat cordate, with a longitudinal median line, and 

 the posterior margin slightly rounded. 



I have described this speeies from Dr. Leach's original specimen in the 

 Bnt.sh Museum. It very much resembles the true Linnean S. morsitans, 

 but ,s d,st.„guished from it by the joints of the posterior pair of legs, which 

 are longer and more slender. There is a ticket to the original specimen, 

 With the name and word " Fantee," in Dr. Leach's hand-writing. These spe- 

 cimens of wh.ch there are several, were brought from the western coast of 

 Atnca by the traveller Bowdich.

I am doubtful whether this speeies is in reality distinct from S. Leachii, 

 which it very closely resembles.
