Loman doos not mention in this connexion A. minutus, 

 Tloek, from wliicli Ortniann distiiiguislios A, hicornis because 

 (among otiiei less important cliaiacters) the former is said to 

 liave an unpaired spine or tubercle at the base of tho chelo- 

 phores. Tiie two type-specimens of Iloek's species, however, 

 have clearly a pair of tubercles in that position (as Loman 

 found also in a specimen referred to this species from the 

 'Siboga' Expedition), and I cannot find any characters by 

 which it would appear safe to separate it from A. hicornis, 



Fiir. 4. 



Ascorhynchus auchtmicris (Slater), holotype. First leg of left side (firat 

 and second coxse from above, distal segments from behind), with 

 enlarfred tiofure of terminal claw. 



While agreeing with Loman that the tubercles or processes 

 on the body and on the coxse of the legs may vary widely in 

 degree of development, I propose to restrict the name A. ra- 

 mipes (Bbhm) to specimens having no claw on the first legs 

 and tlie abdomen about as long as the proboscis, and to a|)ply 

 the name A. auchcnicus (Slater) to forms which have a claw 

 on the first legs and the abdomen not more than half as long 

 as the proboscis. The following synonymy is suggested : — 



Ascorhynchus auchenicus (Slater).
