Kingsley 1 unites his Alpheus transverso-dactylus with 

 A. candei Guerin from the Bermuda Islands and the 

 West Indies, at the same time listing A. damator Lock, 

 as a distinct species. But as Kingsley's description of 

 transverso-dactylus agrees perfectly with damator, and as 

 his specimens came from a locality where that species is 

 abundant, there is no doubt in my mind that Kingsley's 

 species is identical with the latter form. Having de- 

 scribed as damator 2 what was really a distinct species, 

 A. barbara Lock., Kingsley made out of specimens which 

 really belonged to damator a new species, transverso- 

 dactylus. I am unable, moreover, to follow Kingsley 

 when he subsequently unites his transverso-dactylus with 

 A. candei. Candei, according to Guerin, 3 " a la piece 

 basilaire des antennes externes prolongee en une longue 

 pointe qui atteint la moite de la longeur de Pappendice 

 lamelleaux," while in damator this spine does not reach 

 one-third the length of the acicle. In candei " les 

 cuisses des troisieme et quadrieme pattes n'ont pas de 

 dents," while in damator both bear a prominent spine- 

 tooth. The rostrum is smaller in candei than in dama- 

 tor, and there are differences in the form of the larger 

 hand.
