338 Annals of tlie South African 



1896. A. s., Alcock, J. A. S. B., vol. Ixv., pp. 263, 265. 



This species, No. 11426, has been sent me from the Cope 

 by Dr. Peringuey.

 1843. L. s., Krauss, Siidafrik. Crust., p. 53. 



Krauss only says : " Macleay upon a single damaged 

 specimen has established this sub-genus, which is closely 

 related to Philyra, Leach, and probably cannot be separated 

 from it." 



Nos. 161, 162, from rocks at St. James, False Bay, sent by Dr. 

 Gilchrist, appear to belong undoubtedly to this species, as they 

 fully agree with M c Leay's figure. The broad, much advanced, 

 scarcely emarginate rostrum is a conspicuous feature. A female, 

 8 mm. long by nearly 10 mm. broad, showed a very broad pleon, 

 with first segment very short, the last narrow, ovoid, all the inter- 

 mediate segments soldered, but the second with faint suture, not 

 produced to a point on either side as in Stimpson's Carcimispis. A 

 male, with carapace 9 mm. long, 10 - 5 mm. broad, has the pleon 

 narrowly triangular, with forward directed arched lobe on back of 

 penultimate segment.
