but they are probably a little shorter and a little less slen- 

 der. The raeropodites are perhaps a little more enlarged; their 

 upper margin terminates , before the distal end , in a tooth 

 and the inferior margin is denticulate, present- 

 ing , along the distal end , several acute teeth of which the 

 proximal one is the largest and the others gradually decrease 

 in size towards the articulation of the wrist. The ambula- 

 tory legs are somewhat hairy like those of Ses. Andersoni. 

 Our specimen has a reddish ground-colour and the outer 

 surface of the hand is violet.

Two specimens, ^ and 0, from the Island of Ponape. 



Both specimens certainly belong to White's species which 

 was described firstly by Miers and recently by myself, but 

 it appears very probable to me that Eup. sinuatus Stimps. 

 from Sydney is identical with this species. If this is really 

 the case, Stimpson's name has the priority , because White 

 has not published a description. The internal margin of the 

 right hand presents a narrow but rather deep emarginatiou 

 near the articulation of the wrist as well as near that of the 

 mobile finger, so that Stimpson's definition »margine 

 interno ad manus dactylique com mis suras si- 

 nuato" is quite applicable to our species. Both specimens 

 are younger than the specimen from Amboina, lately de- 

 scribed by me, and it is for that reason that the peduncles
