256 Miss D. A. Stewart on the Extra- Antarctic 



Locality. Lat. obs. 13° 59' S., long. 34° 35' W., Sept. 9th, 

 .1901 (near Bahia), one female, 2*5 mm. 



Distribution. Tropical Atlantic (Bovallius) ; the temperate 

 Atlantic and the Mediterranean (Chevreux) ; the Equatorial 

 currents, the Gulf of Guinea, and the Gulf Stream (Vosseler). 



Genus Hyperiella, Bovallius. 



Hyperiella antarctica, Bovallius. 



Hyperiella antarctica, Bovallius, 1887 (i) & 1889. 

 Hyperiella antarctica, Stebbing, 1888. 



Locality. Lat. 56° 30' S., long. 169° 30' E., Dec. 19th, 

 1903, one male, 8 mm., at surface in dredge. Temp, of 

 air 40°, sea 107° Fahr. 



This form agrees in general appearance and in structural 

 details with the description of H. antarctica given by 

 Bovallius (1889), and the form of the uropods particularly is in 

 close agreement with his figure. It is curious, however, to 

 notice the presence of distinct spines on the three segments of 

 the metasome, a character quoted by Stebbing (1888) as being 

 representative of H. dilatata. 



It may also be remarked that Walker (1907) has recorded 

 the capture of II. dilatata from the winter-quarters of the 

 ' Discovery ' Expedition. 



Distribution. The American Antarctic region, lat. 58°40'S., 

 long. 76° W. {Bovallius). 



Genus Hypekioides, Chevreux.

 Hyperioides longipes, Chevreux, 1900. 



Locality. Lat. 37° 33f S., long. 6° 09' E., Sept. 29th, 

 1901 (near Tristan da Cunha), eight examples, 5-7 mm. 



This record of the occurrence of the species indicates a 

 considerable southerly extension of its geographical range. 



Distribution. Temperate and tropical Atlantic (Chevreux 

 and Vosseler) ; the Mediterranean (Vosseler and Chevreux) ; 

 Bay of Biscay (Stebbing) ; W. coast of Ireland ( Walker and 

 2 after sail) .
