WALKER — AMPHIPODA HYPEBIIDEA. 53 



13. Scina borealis, G. O. Sars. 



C. 1200 fms. : foui'. — P. 25 fms. : four, length 5 mm. 



Bovallius (Amph. Hyperiidea, \). 17) says that the exterior rami of all the uropoda in 

 this species are very minute. Tliose of the 3rd pair, however, are as described and 

 tigured by G. O. Sars (Crust. Amph. of Norway, p. 20, pi. 8), fully half as long as 

 the inner. 



Genus VIBILIA, M.-Edw., 1830 



14. Vibilia longipes, Bovallius. 

 e. 200 fms. : one. 



15. Vibilia viatrix, Bovallius. 

 F. Surface : three, length 4 mm. 



16. Vibilia robusta, Bovallius. 



2). 600 fms. : one, length 6 mm. — r. 250/500 fms. : two, 6 mm. 



17- Vibilia gracilenta, Bovallius. 



p. 600 fms. : one, length 6 mm.— r. 250/500 fms. : one.— M. 200 and 300 fms. : three. 



The occurrence of the last two species together on two occasions on the same 

 date suggests some connexion between them. V. gracilenta has the hind corners of the 

 last ural segment produced backwards, which is not the case in V. robusta. 



Genus LANCEOLA, Say, 1818. 



18. Lanceola sayana, Bovallius. 



II. 750 fms. : one. — wn. 200 fms. : one. 

 Botli specimens are imperfect. 



Genus PHORCORRHAPHIS, Stebbiug, 1888. 



19. Phorcorrhaphis raynaudii (M.-Edw.). 

 Phorcorrhaphis edwardsi, Stebbing. 



F. Surface : five, largest 35 mm. — Q. Surface : one, small. 



Genus PLATYSCELUS, Sp. Bate, 1861. 



20. Platyscelus armatus (Glaus). 



II. 750 fms. : one ? , length 8 mm. Amirante, Eagle I., 17/10/05, 209 fms. : one ? 

 with ova, length 23 mm. ; " off sounding-lead." 



Genus HEMITYPHIS, Claus, 1879. 



21. Semityphis crustulatus, Glaus. 



F. 100 fms. : one 6 , 5 mm. — s. 350-0 fms. : one ? , 8 mm. 



The head and gnathopods agree with Glaus's description of the above, but perteopod 5 

 with H. tenuimanus, Glaus. Possibly they are identical.
