Amphipoda Hyperiidea collected by the ' Discovery.' 2<>.'5 



L. robusta, Glaus, and L. pulex, Marion, to judge from 

 published descriptions and figures, do not seem very con- 

 vincing, and I have been led to refer my specimen to 

 L. vincentii mainly because the locality of capture agrees 

 with that of the type, rather than because I am convinced of 

 its separate specific identity from L. robusta and L. pulex. 



Distribution. Off St. Vincent and the Cape Verde Islands 

 (Stebb ing). 



Lyccea sp. 



Locality. Lat. 15° 45£' S., long. 33° 1H' W., Sept. 10th, 

 1901, one female. 



In this specimen the entire urus is missing, so that it is 

 impossible to identify it with any certainty. In all proba- 

 bility it is L. vincentii. 



Family Oxycephalic^, Spence Bate. 

 Genus Streetsia, Stebbing. 



Streetsia washingtoni, Senna ? 



Locality. Lat. 19° 13' S., long. 39° 35' W., Sept. 12th, 

 1901 (S. Atlantic, between Bahia and Rio de Janeiro), one 

 male, 19 mm. 



In many respects this form approaches closely to S. steb- 

 btngi, (Jhevreux (1900), but it differs in several important 

 points, chief amongst which are : (1) the presence of serrations 

 on the under margin of the head ; (2) the inferior margin of 

 the propodus of the first gnathopod is minutely serrated, 

 whereas in S. steblingi it bears four large teeth ; (3) the 

 carpus of the first gnathopod has four large teeth on the 

 palmar margin, instead of only one, and the teeth on the 

 propodus are more pronounced ; (4) the inner distal corner of 

 the peduncle of the second uropod is produced into a to jth 

 instead of being rounded. 



In general appearance and in the structure of the appendages 

 the specimen is in close agreement with S. ivashingto/ii, 

 Senna (1902), but here, again, minor differences occur: (1) the 

 serrations on the rostrum cover a considerably larger area 

 than is represented in Senna's figure, extending at least to 

 the commencement of the eye ; (2) the first gnathopod has 

 several minute serrations on the inferior margin of the pro- 

 podus; (3) the teeth on the propodus of the second gnatho- 

 pod are more pronounced than those of Senna's specimen. 



The rami of the uropods are unfortunately missing, and
