than the others. The first spine is half the length of the second, the third is the 

 longest of all. The first anal spine is opposite the eleventh dorsal. 



The pectoral fins reach well beyond the vent and are as long as the head. The 

 attachment of the pelvic fins is below that of the pectorals. The pelvic fins are two- 

 thirds the length of the pectorals. The caudal fin is rounded ; it is one-fifth of the 

 total length. The lowest five rays of the pectoral fins are separate. 



The body is covered with minute imbricate scales. The lateral line is nearl^^ 

 straight ; it descends somewhat in the region of the tail. 



The gill-rakers are short and obtuse. 



The stomach is caecal, with four short pyloric cseca. There are minute villiform 

 teeth in both jaws and on the vomer and palatines. 



Colour in spirits greyish brown above, lighter below. The dorsal, pectoral and 

 caudal fins have obscure grey spots. There is a greyish blot behind the angle of the 

 opercle. There are two irregular rows of spots*above the lateral line.

Family CI^YCOPTERID^. 

 Genus Liparoides, nov. 



A small tadpole-like fish which shows its relation to the family in possessing a sub- 

 orbital* stay to the preoperculum and a broad attachment of the pectoral fins. It 

 differs from the other bathybial genera of the family in possessing a diphycercal tail 

 and small pelvic fins which are not modified into a sucker. There is one continuous 

 dorsal fin, but the anterior rays differ from the posterior. The dorsal and anal fins 

 are separated from the caudal by a wide space. The line of attachment of the pec- 

 toral fin rays is about as long as the longest ray. The rays diminish in length from 

 above downwards. The pelvic fins are small and are situated close together near 

 the middle line between the lowest ray of the pectorals. The vent is situated about 

 the middle of the body length. The gill-openings are wide, extending from the upper 

 angle of the operculum to the lower end of the attachment of the pectoral fins. Bran- 

 chiostegals seven. Three-and-a-half gills ; no slit behind the fourth arch. A small 

 pseudobranch. 



Teeth in two or three irregular series in both jaws and on the vomer and pala- 

 tines. Skin soft, grey and devoid of scales. I^arge mucous glands open on the head. 

 Eyes are most probably functionless.

 The head is rather less than half the total length without the caudal, the propor- 

 tion being five to eleven. The greatest breadth of the head is equal to two- thirds of
