Comanthus intricata, sp. nov . = Actino7netra intricata Liitken, MS., not Actino- 

 metraintricata mtken, 1874- Comatula rotalaria Lamarck, 18U = Aledo parmcirra 



J. MuUer, 1841. 



With the specimens of Oligometra imbricata was found the name Antedon cupu- 



liferus Liitken, MS. 



The new genus Mastigometra was described, and the new generic name Comanthus 

 appears, under which, in combination, two new species, intricata and decameros, are 

 described. 



The first shipment of crmoids from the work of the Albatross in the Philippine 

 Islands had arrived, and on December 23 a preliminary notice of the species included 

 was published. 



The new species described were : 



Metacrinus zonatus. Cyllometra suavis. 



Catoptometra magnifica. Oligometra gracilicirra. 



Eudiocrvnus serripinna. Calometra carduum. 



Himerometra bartschi. Calometra acanthasfer. 



Himerometra robustipinna. Ptiloynetra trichopoda. 



Himerometra magnipinna. Charitometra smithi. 



Himerometra discoidea. Perometra elongata. 



Himerometra unicornis. Eumetra chamberlaini. 



Himerometra echinus. Iridometra scita. 



Himerometra gracilipes. Trichometra explicata. 

 Pentametrocrinus diomedeae. 

 The new genera included were : 



Comanthus. Comatella. 



Eumetra. 



The new genus Comanthus (genotype Alecto parincirra J. Miiller) was diagnosed 

 as follows: First articulation of the free arm a synartliry; all division series 4(3+4) 

 or 2; terminal comb long, with short teeth, continuing in the same direction as the 

 basal portion of the pinnule, and confined to the pinnules in the proximal part of 

 the arm. This is contrasted with Phanogenitt as restricted, which is rediagnosed as 

 follows: First articulation of the free arm a syzygy; all division series except the 

 first 2(1+2); terminal comb short, with long curved teeth, and set at an angle to 

 the axis of the pinnules, not confined to the proximal pinnules, but occm-ring at 

 intervals throughout the arm. Comatula is said to be readily distinguishable from 

 both by the syzygy between the costals, and Comaster by the presence of a pinnule 

 on the fijst brachial of all arms not arising from costal axillaries. 



The previously described species recorded were: 



Comaster sentosa. Phanogenia multibrachiata. 



Comaster fimbriata. Comanthus nobilis. 



Comaster coppingeri. Comanthus duplex. 



Comatula pectinata. Comanthus divaricata. 



Phanogenia tyjnca. Comanthus rotalaria. 



Phanogenia novae-guineae. Comanthus alternans.
