Locality—Station 5160, Tinakta Island (lat. 5°12’40’’ N., long. 
119°55’ E.) ; 22 meters; February 22, 1908. One specimen. 
Remarks.—This is a fine specimen, 68 mm. long, of nearly oval out- 
line. The petaloid area is only half the test length, the anterior petal 
shightly open. It is, on the whole, a fairly typical example of this 
rather variable species. 
It is generally agreed that it was a very regrettable mistake by Lovén 
(whom de Meijere follows) to use the name rosaceus of Linnaeus for 
this specits. The name vosaceus is to be used for the common West 
Indian species, the genotype of the genus Clypeaster.

Locality Station 5415, between Cebu and Bohol (lat. 10°08’ N., 
long. 123°57’ E.) ; 160 meters; March 24, 1909. One specimen. 
Remarks.—The specimen is a large one, 135 mm. long, and very badly 
broken. I have succeeded in gluing the larger fragments together, 
so that one gets an idea of what it looked like when alive. The distal 
part of the test rises fairly gradually toward the petaloid region, from 
where it rises more steeply. I have specimens of similar shape from 
the Kei Islands, together with such as have the edge flatter, as is 
the rule in the Japanese specimens. JI have no doubt that this specimen 
actually belongs to C. virescens, so widely distributed in the Pacific, 
from Japan to New Zealand. 
The tridentate pedicellariae have slender valves, as I find them in 
a specimen from off New South Wales. (These will be figured in 
volume 4, pt. 2, of the Monograph of the Echinoidea.)
