36 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



Comaster therefore supplants Phanogenia as previously used by rue, and for the 

 genus which I had called Comaster the name Capillaster is proposed with Actino- 

 metra sentosa P. H. Carpenter, 1888, as the type. 



In another note the capture of a small Iridometra nana, which had been attracted 

 to and was swimming about a submerged electric light, was recorded, and in a third 

 Oligometra studeri is shown to be in reality a species of the genus Cyllometra, closely 

 related to C. informis. 



Among the collections stored in the National Museum I had found some very 

 extraordinary comasterids with a central mouth, covering plates along the ambulacral 

 grooves, sacculi, and deficient pinnulation, which were described in great detail on 

 April 27 under the name of Comatilia iridometriformis. A very young specimen 

 showing five large orals and five large interradials lying on the closed radial circlet 

 was described and its affinities discussed at considerable length. 



A second consignment of crinoids from the Philippines was recorded on May 13. 

 The new species described were : 



Phanogenia minima. Ptilometra pulcherrima. 



Phanogenia delicata. Stenometra arachnoides. 



Comanthus polycnemis. Crotalometra eupedata. 



Pontiometra insperatus. Pachylometra levigata. 



Cenometra delicata. Iridometra exguisita. 



The previously known species included are : 



Comaster sentosa. Comanthus alternans. 



Comaster multiradiata. Cenometra unicornis. 



Phanogenia multibrachiata. Stephanometra tenuipinna. 



Phanogenia carpenteri. Cyllometra' manca. 



Comatula pectinata. Oligometra pulchella. 



Comatella nigra. Calometra carduum. 



Comanthus nobilis. Parametra compressa. 



Comanthus briareus. Glyptometra tuberosa. 



Comanthus duplex. Endoxocrinus alternicirrus. 



Comanthus rotalaria. Hypalocrinus naresianus. 



Metacrinus wyvillii. 



Antedon bassett-smithi Bell, 1894, described in the "Spinifera group" of Antedon 

 is identified as Actinometra (Comatella) stelligera P. H. Carpenter, 1888. Comatula 

 nmbriata, Actinometra borneensis and Actinometra coppingeri are placed in the syn- 

 onymy of Asterias (Comaster) multiradiata Linne". Bell's Actinometra variabilis, 

 placed by P. H. Carpenter in the "Parvicirra group" of Actinometra, is in reality 

 closely related to Phanogenia typica. 



A new genus Crotalometra (genotype Crotalometra eupedata, sp. nov.) is described, 

 to which are assigned Antedon valida P. H. Carpenter, A. incerta P. H. Carpenter, 

 and A. magnicirra Bell. 



The infrabasals of Hypalocrinus naresianus are described and figured.
