A MONOGRAPH OF THE EXISTING CRINOIDS 683 



Strait arc in reality C. timorensis. Those from the Red Sea are in reality Comissia 

 hartmeyeri. The specimens on which a number of the other locality records are 

 based, as explained above, include both parncirra and timorensif;. Panope" (Ponape) 

 is inadvertently given as in New Guinea instead of as in the Gilbert Islands. 



In an account of the comatulids in the collection of the British Museum published 

 in 1913 I recorded and gave notes on 33 lots of specimens, most of whirh had previ- 

 ously been noticed by Bell or by Carpenter. One of the specimens from Banda 

 (with about 40 arms) should have been referred to timorensis (annulata}. In another 

 paper published in the same year I gave the known records of this species from 

 eastern Asia. 



Dr. August Reichensperger in 1913 recorded 4 specimens, collected by Doctor 

 Sarasin, from Ceylon; 1, collected by Professor Strubell, from Amboina; and 1, col- 

 lected by Dr. H. Merton, from the Aru Islands. The last is in really timorensis. 



In 1914 I recorded a specimen which had been dredged by the Endeavour between 

 Fremantle and Geraldton, Western Australia, and in 1915 Dr. H. L. Clark recorded 

 a specimen from Ceylon. In another paper published in 1915 Doctor Clark recorded 

 this species from Mer in the Murray Islands, and gave notes on its occurrence and 

 colors in life. 



Dr. Robert Hartmeyer in 1916 published a correction of the catalogue numbers 

 which I had given in 1912 for the specimens in the Berlin Museum from Amboina 

 and from New Guinea, and for some without locality, and in addition listed some 

 fragments without locality in the museum collection. 



In 1918 I recorded and gave notes upon specimens of this species which had been 

 collected by the Siboga at 23 stations, and added a synonymy hi which M filler's 

 Alecto- timorensis was included. Two young individuals were mentioned as having 

 been taken swimming at or near the surface. 



In 1921 Dr. H. L. Clark wrote that this is the most perplexing comatulid found 

 at Mer, for while typical specimens are easily recognized, the intergradations with 

 timorensis (annulata) are very puzzling. 



Doctor Clark remarked that as many specimens of timorensis have only from 21 

 to 29 arms and often have cirri, sometimes XVIII or XIX, it is only by a careful 

 weighing of all the characters that the 2 species can be distinguished. He said that 

 he was by no means sure that they really ought to be regarded as distinct, but on 

 the other hand it seemed to him unwise to include them under a single name. 



In 1922 in his report on the crinoids collected by Dr. Sixten Bock on his expe- 

 dition to Japan Dr. Torsten Gisle'n recorded parvicirra from 2 stations in the Bonin 

 Islands and also from Misaki, Japan. 



He placed as synonyms under parncirra the Comaster multifda and Comaker 

 typica described by him from specimens in Mjoberg's collection in 1919. 



The figure which he published of specimen 2 of Comaster typica (station 13) 

 shows quite a typical example of Comantheria rotula. The other specimen of typica 

 (station 5) appears probably to have been an example of parvicirra. Of the 3 speci- 

 mens incuded under Comaster multifida, the 2 from station 5 appear to represent 

 parvicirra, while the 1 from station 1 seems to be referable to Capillaster multiradititu. 



Gisle'n divided parvicirra into 2 "subspecies" which he called Comanthus (Vania) 

 parvicirra a comasteripinna and Comanthus (Vania) parvicirra ft comanthi pinna, and
