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

 genus which I had called Comaster the name Captllaster is proposed with Achno- 

 metra seniosa P. H. Carpenter, 1888, as the type. ^. ^ . , ^^ ,, , , 



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

 to and was swimmhig about a submerged electric light, was recorded, and m a third 

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



related to C. informis. -r , , p , 



Among the collections stored m 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 detad on 

 April 27 under the name of Comatilia iridometrijormis. 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. 

 Phanogenia delicata. 

 Comanthus polycnemis. 

 Pontiometra insperatus. 

 Cenometra delicata. 



The previously known species included are : 



Comaster sentosa. 

 Comaster multiradiata. 

 Phanogenia multibrachiata. 

 Phanogenia carpenteri. 

 Comatula pectinata. 

 Comatella nigra. 

 Comanthus nobilis. 

 Comanthus briareus. 

 Comanthus duplex. 

 Comanthus rotalaria. 



Ptilometra pulcherrima. 

 Stenometra arachnoides. 

 Crotalomefra eupedata. 

 Pachylometra levigata. 

 Iridometra exquisita. 



Comanthus alternans. 

 Cenometra unicornis. 

 Stephanometra tenuipinna. 

 Cyllometra manca. 

 Oligometra pulchella. 

 Calometra carduum. 

 Parametra compressa. 

 Glyptometra tuberosa. 

 Endoxocrinus alternicirrus. 

 Hypalocrinus naresianus. 



Metacrinus un^mllii. 



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

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

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

 onymy of Asterias (Comaster) multiradiata Linn^. 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 Crotalomefra (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.
