194 HAWAIIAN AND OTHER PACIFIC ECHINI. 



it. Since Mortensen has accepted it and has further identified with Linnets 

 species, Gray's ventricosus, and A. Agassiz's japonicus, the simplest and best 

 action is to concur in this decision and thus attach Linnets name to a form of 

 which enough material is available from known localities to give a satisfactory 

 knowledge of the species. As it has been described and discussed by Loven, 

 A. Agassiz, Doderlein, and Mortensen, there is nothing of importance to add here. 

 The Albatross series is made up of specimens 15-60 mm. in length, all from 

 Japan. The smallest and a specimen 18 mm. long have no genital pores, but 

 they are evident enough in specimens 30 mm. in length. The largest specimen 

 is 54 mm. broad and 44 mm. high; its breadth is thus .90 of the length and the 

 height is .73. Another specimen not quite so large has the breadth .86 of length 

 and the height about .78. 



In the report on the Albatross Hawaiian collection (1907. Bull. M. C. Z., 

 50, p. 259) a very young specimen of Schizaster japonicus is recorded from near 

 Kauhola Light, Hawaii. Further study of this specimen, in comparison with 

 the smallest available specimens of lacunosus make me doubt whether the 

 specimen is a true Schizaster at all. There is no indication of a lateroanal 

 fasciole and I am inclined to think this young individual is probably an imma- 

 ture Brisaster. At any rate it is quite erroneous to consider S. lacunosus a 

 member of the Hawaiian fauna on the basis of this specimen.
