Agulhas Bank, 25-40 fathoms, s.s. Pieter Faure. 



Easily distinguished by its greater slenderness from the Japanese 

 okinoseanus, Dean, 1904, the only other known species with eight 

 gill-openings. 



ELASMOBRANCHII. 

 FAMILY RAIIDAE. 



RAIA SPINACIDERMIS, n. sp. 



$, shape of microps (Giinther, Challeng. Rep. I, Plate IV), but a little 

 broader in proportion to length, and snout sharper. Width equal to 

 distance from snout to middle of tail. Snout pointed but not produced, 

 about 90, anterior margin almost straight, outer pectoral angle broadly 

 rounded, hind margin convex. Eye a little less than interorbital 

 width, which is 3f in preocular length of snout. Internasal width less 

 than distance of nostril from tip of snout. Rostral cartilages narrow 

 and slender, united for a little more than half their length. Anterior 

 rays of pectoral reaching to 25 mm. from tip of snout. Tail a little 

 shorter than length of body ; the lateral cutaneous fold confined to 

 the posterior third. Teeth 60, the median ones slightly pointed. 

 Whole upper surface of disc and upper and lateral surfaces of tail 

 covered with closely-set fine setiform spinules (resembling the skin 

 of Spinax, whence the name), larger and closer on the tail than else- 

 where ; large spines entirely absent ; lower surface of tip of snout with 

 a few spinelets, lower surface of tail, except the median line of the 

 basal two-thirds, with setiform spinules similar to those on upper 

 surface. 600 mm. Pale slaty-grey, becoming slightly darker towards 

 hinder margins of pectorals and distinctly darker on pelvics. Lower 

 surface similar to upper. 



Exact locality unknown, s.s. Pieter Faure. 



This hitherto undescribed species is represented by a $ only, and is 

 noteworthy for the entire absence of enlarged spines. 



ISOSPONDYLI. 

 FAMILY ALEPOCEPHALIDAE. 



ALEPOCEPHALUS AUSTRALIS, n. sp. 



Depth of body 5|-6, length of head 3 in length of body. Greatest 

 depth at level of pectoral. Eye equal to snout, not quite twice
