NO. 2022. NEW STARFISHES FROM THE PHILIPPINES— FISHER. 215 



Type-locality. — Tonquil Island, Gumila Reef, south of Zamboanga, 

 Mindanao. 



This species differs from F. halansx Perrier in having narrower 

 rays, tuberculate marginals, and spatulate furrow spines. 



OPHIDIASTER TRYCHNUS, new species. 



Differing from 0. pusillus Miiller and Troschel in having the papulae 

 in 8 longitudinal series and the central granules of the abactinal, 

 marginal, and actinal plates enlarged, and subtuberculate on outer 

 part of ray, and in havmg the pedicellaria sheaths toothed, not entire; 

 differing from 0. tuherifer in having 8 longitudinal series of papular 

 pores, much larger and broader pedicellariee with the sheaths toothed, 

 not entire, and in having a number of enlarged granules on the plates, 

 not a single conical tubercle of predominant size. 11 = 19 mm., r = 4 

 mm., R= about 5 r; breadth of ray at base, 5 mm. Rays cylindrical, 

 only very slighty tapering, with a blunt extremity capped by a dorsal, 

 convex, roundish terminal plate. Adambulacral plates wider than 

 long, obliquely oriented; furrow spines 2, flattened, the adoral 

 broadly spatulate, roundly truncate, about twice as long as breadth 

 at tip; the aboral slightly shorter, much narrower, slightly tapering, 

 and blunt. Forming a transverse, oblique, adorally trending series 

 with the larger furrow spine, and without intervening granules, there is 

 first a shorter compressed, broad, round-tipped granule, then a longer, 

 much thicker ovoid or acorn-shaped slightly flattened tubercle, about 

 as long as the larger furrow spine, but much more conspicuous. 

 Between these consecutive transverse series there is a transverse series 

 of elongate, bluntly pointed granules; and external to the series of 

 tubercles there is a less regular series of shorter actinal intermediate 

 tubercles, interspersed with a few longitudinally oriented pedicellariae. 

 Relatively large two-jawed, excavate pedicellarise occur in variable 

 numbers on the abactinal, marginal, and actinal intermediate plates. 

 Each jaw is broadly spatulate, semicircular distally, broader than in 

 0. germani, and has 4 or 5 relatively large teeth with corresponding 

 indentations on the edge of the form. 



Type.— C^t. No. 32639, U.S.N.M. 



Type-locality. — Port Palapag, north coast of Samar; no record of 

 depth or bottom, but probably collected on reef. 



LEIASTER ANALOGUS, new species. 



Resembling L. coriaceus Peters in having grooved furrow spines, 

 but differing in having longer, slenderer rays, numerous pedicellarise, 

 and the abactinal papulae in very definitely circumscribed areas. 

 Differing from other species of Leiaster in having channeled furrow 

 spines. R = 125 mm., r=13.5 mm., R = 9r; breadth of ray at base,
