LAGANUM FUDSIYAMA. 47 



solidum is also; the Hawaiian specimens which Mr. Agassiz and I had referred to 

 solidum are almost certainly fudsiyama but it is possible that de Meijere's East 

 Indian specimens are identical with our species diploporum. 



The color of fudsiyama is usually green (at least in alcoholic and dry speci- 

 mens) but ranges from grayish yellow to rich, deep green. In the Hawaiian 

 specimens, the ambulacra on the actinal side are often more or less colored 

 with dark purplish brown, the contrast between ambulacra and interambu- 

 lacra being frequently very marked (PI. 141, fig. 9). The miliary spines are 

 as de Meijere has figured them for conicum except that those I examined had 

 square-cut, and not sloping, tips; the rods (PL 124, fig. 14) widen gradually and 

 are coarsely serrate at tip. Pedicellariae common; ophicephalous like those of 

 depressum, the head setting into a hollow at the top of the stalk (PI. 124, fig. 13). 

 The tridentate pedicellariae are of two kinds; in one the valves (PI. 124, fig. 15) 

 are only .20-.25 mm. long and have a broad rather flat blade; in the other, the 

 valves (PI. 124, fig. 16) are .35-.45 mm. in length, curved as in depressum, 

 and have a mesh-work in the blade. The tuberculation of the test is rather 

 coarse, as is shown in figs. 7 and 8, PI. 127. 



The large series of specimens examined came from the following Albatross 

 stations. Many of them are bare and waterworn and some are not certainly 

 identifiable.
