Northwest coast of Oahu Island 
Anthenoides, Leptogonaster, and Antheniaster are very closely related. The arrangement of the ■ ! 
dorsal plates appears to be essentially the same in the three genera, which are likewise characterized by 
a granulous membrane. The type of adambulacral armature of Leptogonaster is essentially that of the 
distal portion of the ray of Antheniaster epixanthus, and the pedicellarise are strikingly similar, these I 
being reduced to the elongate variety in Antheniaster. The dorsal membrane of the latter is not so ' f 
granulous as in Leptogonaster , but is thicker, at least in the Hawaiian species. The mouth plates 
are prominent, but more heavily covered with membrane than in Leptogonaster, and likewise bear ! 
more granules. These three genera do not appear to belong under the Goniodiscidinse, which are j 
probably more nearly related (so far as Goniodiscides is concerned) to the Pentacerotidse than to the j 
typical goniasterids. 1 have accordingly placed Antheniaster in Perrier’s Leptogonasterinee. This 
subfamily, is of course, closely related to the Goniasterinse, and not, as its author believed, to the I 
Mimasterinse or Odontasteridse. I am indebted to Prof. A. E. Verrill for the generic determination j 
of this species.

This genus is equivalent to that long known as Goniodiscus. Under existing rules of nomenclature 
Goniodiscus is untenable because :it was proposed by Muller and Troschel to include previously 
described genera of Gray ( Anthenea , Nectria, Tosia), as well as species unknown to Gray. If this Bj 
group had really constituted a genus the oldest name, Anthenea, should have been used. Likewise the ' I 
type (first species) of Goniodiscus is the same specie 3 , under a different name, as the type of Gray’s : 1 
Anthenea. Muller and Troschel included the following species under their Goniodiscus: Pentagonulus ’ j 
[Anthenea], sebse, placenta [Tosia ], regularis [unknown], pleyadella, ocelliferus [Nectria'], cuspidatus, 1, 
mammillatus [Tosia], capella [since made the type of Ogrnaster v. Martens], This left sebse, regularis (?), U 
pleyadella, and cuspidatus. Goniodiscus has subsequently been used for these species, but since the I 
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 appears to be no subsequent name a available, I propose Goniodiscides, 
with Goniodiscides sebse as type.

An example of this curious species, the first from the Hawaiian Islands, 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 specimens were secured by the expedition of 1902. 
aMetopaster Sladen (Monog. on Brit. Fossil Echinod. from Cretaceous, ii, Asteroidea, pt. ii. <Pal. Soc. Monog. 1893, 
p. 13) is near this genus, but is hardly identical, as has been claimed. (Valette, Note sur quelques Stellerides de la Craie ■ 
Senonienne du D6p. de P Yonne. <Bull. Soc. 1’ Yonne, lvi, 1902, p. 7.)
