ECHINODERMATA. 1 1 9 



Echinoidea," I directed attention to the marked discrepancies which 

 obtained between the descriptions given by Louis and Alexander 

 Agassiz respectively of the species known as S. gldbator. I then 

 figured and gave careful descriptions of the tests of two forms 

 which I distinguished as form a and form (3. I adopted that course 

 in the hope that Prof. Alexander Agassiz Avould explain the reasons 

 which had led him to omit any notice of the species referred to by 

 his father. In the 'Challenger' Report the species is merely 

 recorded, and reference made to the ' Catal. Itaisonne' of Agassiz and 

 Desor ; fortunately the specimens are now in the British Museum 

 collection, and an inspection of them is, of course, sufficient to show 

 the characters of the form which Mr. Alex. Agassiz looks upon as 

 being S. globator. I find them to be examples of what I have 

 called form a, or, in other words, they are not representatives of 

 L. Agassiz's species globator. 



As the species reappears in the ' Alert ' collection, it has been 

 necessary to direct attention to the various points and to propose 

 a name for the species. No appellation will, I think, be more suit- 

 able than that of ah. raw I 'ri ; and, at the time of giving a definite 

 name, one is also able to have the pleasure of adding a definite 

 locality. 



West Island, Prince of Wales Channel.

One of the specimens (diameter 18 # 5 millim.) has all the spines 

 which are preserved on it perfectly white, without any bands what- 

 ever. Smaller specimens in the British Museum collection have a 

 number of, but not one has all, its spines thus totally white.

A good series, with the general colour of the spines dark, and 

 not light, ringed with red as in the specimens from the Japanese 

 seas.

This is one of the most important of Dr. Coppinger's finds, for 

 with the exception of a single, though perfect, test in the collection 

 of the British Museum, which was obtained by Sir E. Belcher off 

 Borneo, and presented by the Admiralty in 1844, no complete 

 example had ever been examined till the return of the ' Challenger.' 

 The largest specimen taken by Dr. Coppinger is a little larger than
