gill-membranes being separate throughout : gill-laminae very narrow : 

 gill-rakers on the outer side of the first arch numerous (over 25 in 

 number), close-set, long, setiform : pseudobranchiae moderately large. 

 Scales small and extremely thin ; larger and even thinner, but sparse 

 and deciduous, on the head. No lateral line whatever. 



The dorsal fin begins well ou the occiput, and is much more deve- 

 loped than the anal, its rays in its anterior two-thirds being more 

 than half of the greatest body-height in length : the caudal, which is 

 only about one-third the length of the head, is confluent with the other 

 vertical fins. Pectorals large and pointed, with a thick fleshy base : their 

 length is nearly equal to that of the postrostral portion of the head. 

 The venfcrals arise close together at the pectoral symphysis : each consists 

 of two long rays, the inner of which is an eye-length longer than the 

 head. 



Intestine long and much convoluted : 7 or 8 very small pyloric 

 caeca : a large air-bladder. 



Colours in spii'it : head and eye and body silvery, the body finely 

 peppered with black : vertical fins hyaline with blackish tips, pectorals 

 blackish, ventrals white. 



The largest specimen is nearly 5| inches long.

Further specimens (from the Bay of Bengal 145-250 fms.), to- 

 gether with a better knowledge of the family, convince me that the 

 characters upon which the genus Pycnocraspedum was founded are not 

 of generic value. I therefore withdraw the name Pycnocraspedum.
