Crustacean Fauna of South Africa. 235 



The 6th joint of the 2nd gnathopod of <$ is not always as elongate 

 as represented in Dana's figure, but the proportion of palm to hind 

 margin is the same. 



First and second guathopods in both sexes with the 2nd joint but 

 not the 3rd apically expanded into a rounded lobe. 



Length : Up to 10 min. 



Colour : Pale pinkish, brownish or greenish, eyes black.

HYALE MACRODACTYLA Stebbing. 



1899. Hyale macrodactylus Stebbing, Tr. Linn. Soc. Lond. ser. 2, 



vol. 7, pt. 8, p. 404, pi. 31o. 

 1906. Stebbing, Das Tierreich, 21, p. 564, fig. 96. 



The form described in 1901 by Chevreux (Mem. Soc. Zool. Fr. 

 vol. 14, p. 397, figs. 13, 14) from Seychelles seems quite distinct 

 enough from Stebbiug's form to merit a separate specific name. 

 Chevreux himself was half inclined to this view. I propose the 

 name H. Chevreuxi. 



The Cape specimens agree well with Stebbiug's descriptions and 

 figures except that they reach a rather larger size and there is some- 

 times a very short, but appreciable and well marked, hind margin to 

 the 6th joint of the 2nd gnathopod of <$ . The finger also is rather 

 variable and is scarcely as long as in Stebbiug's specimens. 



There is a short upstanding seta on both lobes of the telson. 



Length : Up to 8 mm., ovigerous ? 5 mm. 



Colour : Pale pinkish or brownish.
