existing nues of uomencljxturo Gonùxliscus is imteuable because it was pro- 

 posecl by MÜLLi^E aucl TroscheTj to include previously described genera of 

 Gray (Anthenea, Nectria, Tasia) as well as species unknown to Gray. If 

 til is group had reallj' constitut^^d a genus the oldest name, Anthenea, should 

 have been used. Likewise the type (first species) of Goniodiscus is the same 

 sjjecies, under a different name, as the type of Gr.\y's AntMnea. Müller and 

 TiiosCHEL included the following species under their Goniodiscus : Pentago- 

 mdm [Ajithenca], .selxe, placenta [Tasla\ regularis [unknown], joleyadella, ocel- 

 lifcrm \^Ncctria\ cuspidatus, mammillatiis [Tb-Sia], copdla [since made the 

 ty[)e of Ogtiiaster v Martens]. This left S'jIxjb, rcgularis{?), pleyaddla, and 

 cuspidatus. Goniodiscus has subsequently l3een used for these species, but 

 since th«; name was originally applied to a composite group and was a 

 synonym as soon as made, it should be discarded for all time. As there ap- 

 pears to be no subsequent name'^ available I propose Goniodiscides, with 

 Goniodiscides sehœ as type.

" An example of tliis cmious species, the first from the Hawaiian Is- 

 lands, was taken by Mr. H. W. Henshaw at Hilo, on the windward side 

 of the Island of Hawaii. (Accession no. 42800, U. S. Nat. Mus.) No speci- 

 mens were secm-ed by the expedition of 1902. 



" Concerning the capture of this specimen, Mr. Henshaw has sent me 

 the following notes : ' They are by no means rare in a small inlet some tlu-ee 

 miles south of Cocoauut Island. If I remember rightly, all I found were 

 under stones in shallow Avater, two or three feet deep. In other words, so 

 far as I have observed it, it was a littoral, sliallow A\ater species.' Tliis is 

 the only species of starfish, so far as I am aware, that may be collected 

 along shore in the islands, unless Ophidiasfcr lorioli be excepted.
