NO. 2022. NEW STARFISHES FROM THE PHILIPPINES— FISHER. 203 



LUIDIA ORIENTALIS, new species. 



Related to L. sarsi Diibeii and Koreii, L. africana Sladen, and 

 L. asthenosoma Fisher. Closely resembling L. asthenosoma, from 

 which it differs in having deeper and broader marginal fascioles, 

 slightly longer mferomarginal and adambulacral spines, longer 

 inferomarginal spinelets, and actinal intermediate pedicellarise taper- 

 ing slightly when seen from side (untapered or obovate in astlieno- 

 soma). Rays 5. R = about 120 mm., r = about 14 mm. The tip of 

 ray is regenerating so that the original was considerably longer; 

 breadth of ray at base, 15 mm. 



Type.— Csit. No. 32623, U.S.N.M. 



Type-locality. — Station 5301, China Sea, vicuiity of Hongkong 

 (lat. 20° 37' N.; long. 115° 43' E.), 208 fathoms, gray mud, sand, 

 bottom temperature 50.5° F. 



L. orientalis differs from L. sarsi in having longer paxillar, marginal, 

 and actinal spines, broader and deeper margmal furrows. It differs 

 from L. africana, which represents elegans on the east side of the 

 Atlantic, in having broader inferomarginal fascioles, longer infero- 

 marginal spinelets, more tapered actinal pedicellariae, and agrees with 

 it as well as with asthenosoma m having longer rays than sarsi. 



LUIDIA AVICULARIA, new species. 



Very closely related to L. integra Kcehler, which it resembles in 

 general appearance but from which it differs in the following particu- 

 lars: Scattered spinopaxillse among the normal paxillas of the 3 

 dorsolateral series; superomarginal and abactinal paxillse with small 

 two-jawed pedicellariae ; central spinelets of superomarginal and 

 abactinal paxillse, sharp, longer than thick, not granuliform; infero- 

 marginals encroaching conspicuously upon abactinal area and with 

 marginal spines varying from 2 to 6; inferomarginal pedicellarise 

 present on some of the plates; the characteristic furrow pedicellarise, 

 proximally with dorsal jaw curved over end of the slightly curved 

 ventral jaw; proximal adambulacral plates with generally more than 

 3 spines, and more than 1 subambulacral pedicellaria, pedicellarise 

 sometimes replacing the spines; generally 2 large dental pedicellarise, 

 directed over the peristome. Rays 10. R = 195 mm., r==18 mm., 

 R = 10.5 r; a shorter ray, R = 175 mm.; breadth of ray at base, 13 

 mm.; breadth 15 mm. from base, at widest part, 17 to 18 mm. Ray 

 gradually tapering, blunt, abactinal surface slightly convex. 



Type.— C&t. No. 32624, U.S.N.M. 



Type-locality. — Station 5391, between Samar and Masbate (lat. 

 12° 13' 15" N.; long. 124° 05' 03" E.), 118 fathoms, bottom unre- 

 corded; 1 specimen. 



L. integra Koehler was taken by the Investigator, off the Andaman 

 Islands (lat. 13° 06' N.; long. 93° 08' E.), 60 to 75 fathoms.
