50. Alpheus candei Guerin. 



Guerin, in Sagra's Histoire de I'isle de Cuba, Paris, p. L, pi. 

 II., fig. 9, 1857. 



Alpliciis trmisverso-dactyliis Kingsley, Bull. U. S. Geol. Sur- 

 vey, IV. (no. I.), p. 196, 1878. 



Seven specimens of a yellowish-green color with darker green 

 carapace broken out of coral rock in Castle Harbor '97 and '98. 



The description given by Kingsley (1. c. supra) of specimens 

 from California corresponds very closely to Guerin' s figure of 

 his specimens from the coast of Cuba and to my material from 

 Bermuda. I think there can be no doubt that A. transverso- 

 dactylus Kingsley should be considered as a synonym of A. 

 candei Guerin. Kingsley himself says " I cannot separate from 

 this, i. e., the Californian A. transverso-dactyhts, two specimens 

 from Bermuda, one collected by J. M, Jones and the other by 

 G. Brown Goode." This species comes near A. streptocJiirus 

 Stimp. from the Cape Verde Islands. 



Reported by Kingsley from Goode and Jones collections. 



Distribution : California ; West Indies. 



51. Alpheus lancirostris n. sp. 



(Plate XVII., Fig. 5.) 



Nineteen specimens, 11 ^ , 8 9 ; two from dredger '97, the 

 remainder from under stones in Bailey's Bay, at low tide, '98. 



Carapace smooth. Rostrum prominent, laterally compressed 

 and slightly bent down at tip, extending backward as a sharp 

 lance-like keel to the posterior region of cornea where it broad- 

 ens out to a triangular base ; the keel is separated from the ocu- 

 lar lobes by a broad and well marked sulcus. Ocular lobes prom- 

 inent dorsally ; no spine, but slightly angular anteriorly. 



Inner antennae : basal joint of peduncle reaching to the tip of 

 rostrum, with a sharp spine equal in length to the basal joint ; 

 two following joints cylindrical, the third half the length of sec- 

 ond ; upper flagellum short and stout, tipped with a long pencil 

 of hair ; inner flagellum rather more than twice the length of 

 outer. Outer antennae : basal joint of peduncle with short spine ;
