450 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



The specimen from Zamboanga determined by Carpenter as Comanthus parvicirra 

 had apparently 21 arms. One cirrus remains, which has 12 segments. The charac- 

 teristic terminal combs and the presence of combs on the distal pinnules show that 

 this is a species of Comaster and not of Comanthus. 



Abnormal specimen. In the largest specimen from Siboga station 305, one of the 

 cirri is curiously modified. (See vol. 1, pt. 1, fig. 320, A, p. 275.) It is composed of 

 8 segments and measures 5 mm. in length. The first 3 segments are of the normal 

 type, but those following are strongly flattened dorsoventrally and greatly broadened, 

 the normal distal dorsal spine being represented by 2, 1 at each of the distal angles 

 of the segments.
