has shown that Alcock's species Pentacheles Hextii is a synonym 

 of P. typhlops, so that the range of the species is extended to the 

 Lidian Ocean. 



Norman (1879) gives a description of two specimens of Poly- 

 cheles taken by the Porcupine, one, a male, off the Portuguese 

 coast, and the other, a female, on the Atlantic slope west of the 

 EngUsh Channel (48° 13' N., 9° 11' W.). The male appears 

 from the description to belong to P. typhlops, but the female 

 certainly does not.* 



Vertical Distribution : — -Riggio records a Mediterranean speci- 

 men from about 55 fms., but usually the depths are very much 

 greater. Senna's specimens were taken in 358-848 fms., and 

 Adensamer's in 339-1122 fms. The depths at which the Helga 

 has taken this species range from 208 to 728 fms. 



Irish Distribution : — The species has not previously been 

 recorded from British waters. All the specimens were found 

 oif the south-west coast.

 Kemp, and was referred by him to P. sculptus.
