58 THE BEACHYURA. 



Trapezia cymodoce (iierbst). 



The variations shown in the collection from the South Pacific Islands 

 make it necessary to unite under one specific name the many forms of the 

 cymodoce ferruginea group. ( Cf. Alcock, 67. pp. 219-222.) 



Trapezia cymodoce dentata (MacLeay). 



Trapezia ferruginea dentata Ortmann, Zool. Jahrb., Syst., 1897, 10, 204. 



Rangiroa, Paumotus; beach; Sept. 21, 1899; 1 <?. 



Fakarava, Paumotus; outer reef ; Oct. 12, 1899; 1 <?. 



Makemo, Paumotus ; reef; Oct. 21, 1899 ; 4 <?, 6 9 (5 ovig.). 



Borabora, Society Group ; fringing reef ; Nov. 17, 1899 ; 1 9 ovig. 



Funafuti, shore ; Dec. 25, 1899 ; 1 9, ovig. 



These are but slightly removed from T. cymodoce ; they lack the acute upper 

 border on the palm, and the hairy coating on the outer face of the palm. 



Funafuti; reef; Dec. 24, 1899 ; 5 S, 8 9 (4 ovig.), 3 juv. ; varying toward 

 T. cymodoce. The outer face of the chelipeds is densely covered with downy 

 hair, but the upper edge of the palms is obtuse, and the teeth of the front 

 are not deeply separated.
