mucous coat at the expense of both the mucous and the 

 muscular coats. The mucous coat is made up of the compact 

 ramifications of an acino-tubular gland lined with granular, 

 large-nucleated, cubical epithelium. 



(4) The mucous membrane of the posterior part, which is 

 rather over one fourth of a millimetre thick, is formed entirely 

 of long tubular glands packed close together, side by side, at 

 right angles to the surface. These glands, which much 

 resemble mammalian gastric glands, are lined with a granular 

 cubical epithelium having large prominent vesicular nuclei ; 

 they have broadish mouths, and in their deepest third they 

 end by subdividing into two or three long sinuous branches, 

 which lie in a plane parallel to that of the rest of the gland.

This species, like the next mentioned, seems to be charac- 

 teristic of the Bay of Bengal between 200 and 400 fathoms, 

 occurring in almost every haul.

I leave this species for the present in the genus Nettastoma. 

 The tissues are very delicate, and though in some specimens 

 the air-bladder is very distinct, in others it is hard to dis- 

 tinguish.

Two good specimens were obtained, one, 15 inches long, 

 from Station 126, 1370 fathoms, the other, 13 inches long, 

 from Station 128, 902 fathoms. 



From an examination of these specimens in the fresh state, 

 the following remarks must be added to the description of the 

 mutilated and distorted (type) spirit-specimen : — 



The long lash-like tail is between two and a half and two
