NO. 1561. NEW UNSTALKED CRINOIDS— CLARK. 155 



T}/pe.~Cat. No. 22657, U.S.N.M.; from A/hafros.'^ station No. 481)5; 

 32- 3;r 10" north latitude, 128° 32' 10" east lono-Jtude (south(>rn part 

 of the Sea of Japan); 95 fathoms; August 9, r,)0(). 



Another specimen, from station No. 4893, is somewhat smaller, but 

 otherwise agrees perfectly witli the t^^pe. One of the raj's, however, 

 has the distichal series of only two joints, united by syzygy, like the 

 palmars; neither of the specimens has the disk in position. 



34. COMATULA ORIENTALIS, new name. 



In the Challenger" report on the Coniatuhe Dr. P. Herbert Carpenter 

 gave the name Actlnornetra Hltnple.r to a cui'ious little species from 

 the Admiralty Islpaids; in 1881, however,^ he stated that in the Paris 

 Museum he found specimens of Comatula jparvicirra bearing the name 

 of G. ahnjplex. He mentioned certain peculiarities of these specimens, 

 showing how they differ from Miiller's original description of Alecto 

 parirleirra, thus making it clear that the}' can not belong to the Chal- 

 lenger species to which he gave the name Actmometra shnple,!'. As the 

 two are congeneric, however, it becomes necessar}^ to designate the 

 species described in the i 'hallenger report b}' a new name, and for it I 

 propose the name Coiiiatula orlentali^. 



35. ATELECRINUS POURTALESI,' new name. 



In 1869,'' L. F. de Pourtales described Aiitedon cahenKix from two 

 specimens dredged in 450 fathoms off Cojima, near Ilabana, Cuba; but 

 his description is applical)le ordy to the larger and more perfect speci- 

 men. Although later he seems tt) have suspected that the two were 

 different, he never gave a name to the smaller form. 



In 1881'' Doctor Carpenter, in his preliminary report on the Comatu- 

 lidae collected by the United States Survey Steamer Blal'e^ showed that 

 the smaller specimen was not only specifically but generically distinct 

 from the larger one, and he proposed the genus Aielecrinas for it and 

 an allied forni, also from Cuba, whi(di he called Atelecrlnus cuhensis 

 and Atelecrlnus halanoldes^ respectivel3\ The name cuhensis he credits 

 to Pourtales, sajang that the species "may retain the name cuhensis, 

 originally conferred upon it hy Mr. Pourtales." But, although the 

 Antedon cvl>ens!s was a composite species, the type specimen is clearl}- 

 indicated in the the original description, and it is quite a different
