130 HAWAIIAN AND OTHER PACIFIC ECHINI. 



which ought really to date from 1874. As Mortensen has pointed out, jeffreysi 

 is characteristic of the cold area of the Norwegian Sea and the northeastern 

 Atlantic, where the Ingolf secured 184 specimens. 



Pourtalesia alcocki. 



Koehler, 1914. Ech. Indian Mus. Spat., p. 8. 



This species was collected by the Investigator in the Gulf of Oman at a 

 depth of 1299 fms. It is very near the two following but Koehler compares 

 it more particularly with jeffreysi from which it is undoubtedly distinct. 



Pourtalesia laguncula. 



A. Agassiz, 1879. Proc. Amer. Acad., 14, p. 205. 



This is the only species of the genus represented in the Albatross collec- 

 tions, if we except one small specimen of tanneri, and one large fragment from 

 Station 4766 which is probably different but is too incomplete for identification. 

 Nearly all the Albatross material is in poor condition but there are a few whole 

 specimens and some are really good. On these I found many ophicephalous 

 pedicellariae but no rostrate. On the large fragment from St. 4766, there were 

 two rostrate pedicellariae similar to those of miranda, but no ophicephalous 

 were found. The fragment includes the anal snout which is dorsally flattened 

 and 10 mm. wide.
