nineteen inches from the tail. The proportions of the head are exactly as in Vaillant's 

 specimen, which was taken from 2,200 metres off Morocco. Registered No. --^-. 



Serrivomer sector, Garman. 

 Mem. Mus. Comp. Zool. Harvard, No. xxvi, vol. xxiv, p. 320 (1Ö99). 



This specimen agrees exactly with Garman's detailed description, but it also 

 agree* with the shorter description of 5. heanii (Gill and Ryder). 



Brauer records Serrivomer sector as having been taken by the ' •' Valdivia ' ' from 

 the Indian Ocean, and remarks the similarity between S. sector and S. heanii. Arabian 

 Sea, off Travancore. Station 306, 930 fathoms. Registered No. ^^^^. 



Family ANGUlLIylD^. 



Coloconger raniceps, Alcock,

Among many specimens of this species are three from Stations 323 and 333 

 which are of unusual size, being over 30 cm. in length. They are black in colour but 

 otherwise resemble the smaller specimens of the species, which are greyish brown. 

 The generative organs of these three specimens are conspicuously ripe. They are 

 probably the sexually mature form of the species which, as in certain other eels, is 

 different in appearance from the immature form. Registered No. iöao^i 



Family SYNAPHOBRANCHID^. 



Synaphohranchus pinnatus, var. hrevidor salis, var. nov. 

 Illustr. Zool. "Investigator," Fishes, plate xlvii, fig. i (1909). 



This variety closely resembles 5. pinnatus in all but one character, namely, the 

 length of the dorsal fin. In this it resembles 5. brevidor salis. 



In describing the position of the dorsal fin the same words may be used as in the 

 description of 5. hr evidor salis : "The dorsal fin commences so far behind the vent 

 that the distance between its origin from the vent equals the length of the head." 

 (Günther.) 



In its general proportions and in the mosaic-like arrangement of the elongated 

 scales the specimen resembles 5. pinnatus and differs from brevidor salis. 



There are three specimens of 5. pinnatus from separate stations in the Arabian 

 Sea. In all of these the dorsal fin arises about a head-length and a third behind the 

 gill-opening ; in this specimen it arises rather more than two head-lengths behind 

 that point. *
