the sheath, like the second form, hut at a greater distance from the 

 orifice. 



With regard to the habits of the species, it appears that Chiho- 

 nerpeton indistinctum and Hypographis rostratus have been found 

 living in society at considerable depths in the earth ; whilst other 

 species were observed in the East Indies by Colonel Beddome under 

 stones, and T yphlonectes compressicaudus and natans have been found 

 swimming in fresh water. The branchiferous young of Ichthyophis 

 qlutinosus has also been taken in the water. 



Prof. Peters gives the following Table of the genera : — 



I. Lepidocjecili^:. — Skin with tile-like scales, 

 at least on the margins of the folds ; man- 

 dibular teeth in two rows. 



A. Extremity of the body pointed; tentacle

 angle in the middle of the belly ; ten- 

 tacular pit near the buccal margin, be- 

 tween eye and nostril 1. Ichthyophis. 



b. Body cylindrical ; tentacular pit under 



the nostril 2. Urceotyphlus, g. n. 



B. Extremity of the body rounded off.

The genus Ichthyophis, Eitzinger ( = Epicriwm, Wagler), includes 

 three eastern species — namely, /. ylutinosus, Linn., I. monochrous, 

 Bleek., and /. Beddomei, sp. n. Beddome's Epicrium carnosum, 

 Gegenes carnosus, GHinth., is regarded by Prof. Peters as founded 

 upon very young, immature animals, which, from their cylindrical 

 form and the position of the nostrils, seem to approach Cm'dia rather 

 than Ichthyojdiis. As the generic name Gegenes has long been pre-
