PILUMNIDAE. 59 



The following specimens are similar to the last, but the spots on the legs 

 are absent, perhaps obliterated from long preservation : 



Fakarava, Paumotus; shoal in lagoon ; Oct. 11, 1899; 1 <?, 1 9 ovigerous. 

 Borabora Id., Society Group; fringing reef; Nov. 17, 1899; 1 <?.

Trapezia ferruginea var. areolata Alcock, 1898, 67, 221. 



V avau ; reef; Dec. 5, 1899; 1 i, 1 9 ovig. 

 Funafuti; reef; Dec. 24, 1899; 3 $, 2 9 (1 ovig.). 



Trapezia cymodoce maculata (MacLeay). 



Trapezia maculata Alcock, 1898, 67, 221. 



Makemo, Paumotus ; reef ; Oct. 21, 1899; 1 9 immature; spots few. 



Variety : — At the same locality, an immature 9 agreeing entirely in form 

 with the above, but with quite different markings ; the carapace and cheli- 

 peds are covered with reticulating brown (in alcohol) lines, legs dotted with 

 minute spots of brown. 



Of the form maculata, it may be said that it usually has the prominent 

 front, the sharp side-tooth, the carpal spine, and the brilliant spots on cara- 

 pace, chelipeds, and legs ; but these characters run into those of the inter- 

 media form, which has a less prominent front, blunt side-tooth, blunt-angled 

 wrist, reticulated palms, while carapace and legs are spotted.
