There is a. minute pigment spot at the base of each of the 

 dorsal, caudal, and anal fin-rays, otherwise the animals preserved 

 in spirit are of a creamy colour. When alive they were quite 

 pellucid, but could just be distinguished swimming in the muddy 

 water. 



Specimens obtained in a small beam-trawl at Doorakara, 

 Sunderbans (Gangetic Delta), Bengal, on 15th and i6th of March 

 1918.

We have much pleasure in naming this species in honour of 

 Mr. Milne, M.A., I.C.S., Director of Agriculture, Bihar and Orissa, 

 in recognition of much assistance rendered to the Fisheries 

 Department. 



Leptocephalus vermicularis, sp. nov. 

 (PI. XVI, figs. 2, 3.) 



This species, instead of having the usual band-like form, is 

 rounded like a worm. 



Description. —Number of segments in a specimen, 122. 



Length 61 '2 mm. ; height 4*1 mm. ; head 4*3 mm. ; distance 

 of anus from the end of the tail, 37*8 mm. ; eye "6 mm. ; snout i"i 

 mm. ; post temporal part of the head I'S mm. Height I4'9, head 

 14*2, tail I "6 times in total length. Snout acutely rounded, lead- 

 ing gradually to the post temporal portion which is very broad, 

 even more so than the body. Eye 7*2 times in the head, about 

 half the size of the snout and three times in the post temporal por- 

 tion of the head. 



Gape of the mouth extends a little behind the eye. Anus 

 below the 47th segment, its distance from the tip of the tail being 

 one and a half times the distance from the snout. Minute teeth 

 on the upper jaw, none on the lower. Small rounded pectoral 

 fins. The dorsal, caudal and anal fins rather small, with a large 

 number of fin-rays, three to each myosegment. 



There is a minute black spot at the base of each fin-ray, and 

 a large number of scattered pigment spots, specially collected in 

 groups on the ventral surface of the body. These pigment spots 

 are visible only when specimens are examined under a high 

 magnification, otherwise the specimens appear of a creamy colour 

 when preserved. When alive they were quite pellucid and wriggled 

 very quickly in the muddy water. 



Only two specimens were obtained along with those of the 

 other species described above, in a small beam-trawl at 

 Doorakara, Sunderbans, Gangetic Delta, Bengal, on the 15th and 

 i6th of March 1918.
