appellation which, according to Mr. Gosse, is, in the leeward 

 part of Jamaica, now applied to a species of Mahouia (Nat. Soj. 

 p. 75) ; though it would appear, from what he elsewhere says, 

 that by Sloane and others this term was used for some of the 

 Geccotida (Proc. Z. S. L. 1848, p. 60; Ann. and Mag. N. H. 

 1850, p. 344).'^

 sputator, West, not L.). 



" The Mahouia is known in St. Croix as the ' Slippery-back ' 

 and some of the dread which is inspired by the last-mentioned 

 is also experienced of this species by the negroes. It is supposed 

 to fasten upon the hand or other exposed part of the body with 

 its mouth ; and they assert that there is no way of making the 

 creature let go its hold, save cutting it up, if it once seizes 

 upon one. It is more plentiful than the Thecadactylus, but still 

 not often observed. Two of the examples sent to the Museum 

 were caught in copula.^'

Snout moderately elongate and depressed, with the canthus 

 rostralis sharply prominent, and with a pair of ridges arising 

 from the superciliary margins ; a slight groove between these 

 two ridges, another between each ridge and the canthus rostra- 

 lis ; loreal region rather concave, with five series of very small 

 shields ; the space between the orbits is covered with two series 

 of shields only ; occipital shield distinct. Scales on the sides of 

 the body granular, gradually becoming larger towards the dorsal 

 line and the belly, where they are distinctly keeled. No pro- 

 minent dorsal crest, but two or three series of larger scales along 

 the vertebral line. Pouch of the throat present, moderately 

 developed. Tail slightly compressed, verticillated, above with 

 a low serrated ridge, beneath with strongly keeled scales of equal 

 size. Greenish olive (in spirits), irregularly spotted with blackish 

 brown on the sides and on the posterior parts of the hinder 

 extremity. Female sometimes with a broad whitish dorsal 

 streak, crossed by narrow black bars. 



Description. — The snout is moderately depressed and slightly 

 elongate, the distance between the two anterior angles of the 

 orbit being three-quarters of the distance between the orbit and 

 the extremity of the snout ; anteriorly it is rather narrow and 

 rounded. The canthus rostralis is sharp and rather prominent ; 

 and there is another pair of low divergent ridges, arising from 

 the superciliary margin of the bony orbit, and extending to the
