15 mm. Rays unequal, the longest 8.5 to 9 times as long as the 

 width at base. 



Type.—C&L No. 32640, U.S.N.M. 



Type-locality. — Station 5165, off Observation Island, Tawi Tawi 

 Group, Sulu Archipelago, 9 fathoms, coral. 



L. analogus differs from L. leachii in having perfectly smooth plates, 

 not finely granulated ones, in having more numerous and grooved 

 adambulacral furrow spines, and in having abundant pedicellarise. 

 L. speciosus is described as differing from L. leachii only in possessing 

 pedicellarise. Apparently L. analogus bears much the same relation 

 to coriaceus that speciosus does to leachii. L. glaher and L. callipeplus 

 lack pediceUarisB and have furrow spines without grooves. 



Family ASTEROPID^. 



MARGINASTER PAUCISPINUS, new species. 



Differing from M. capreensis (Gasco) [M. fmhriatus Sladen] in 

 havmg no actinal intermediate and very few abactinal spinelets, 

 broader marginal plates with slightly longer spines, more distinct 

 lobes to the carinal plates, and 2 narrowly spatulate, webbed, sub- 

 ambulacral spinelets in a longitudinal series near the furrow margin; 

 furrow spines 2 on the first 2 plates, then 1. R = ll mm., r = 8 mm., 

 general form arcuate pentagonal; whole body overlaid by skin; a 

 few carinal, apical, and superomarginal spinelets, aU inconspicuous, 

 a conspicuous marginal fringe of webbed, flattened, narrowly spatulate 

 spines; plates not superficially visible. 



Type.—O&t. No. 32641, U.S.N.M. 



Type-locality. — Station 5310, China Sea, vicinity of Hongkong 

 (lat. 21° 33' N.; long. 116° 13' E.), 100 fathoms, sand, shells. 



Family GANERIID.E. 



TARACHASTER, new genus. 



Rays slender, disk small; dorsolateral plates four-lobed, imbricated 

 in regular transverse and longitudinal series; plates of median radial 

 region mostly three-lobed, irregularly imbricated; marginal plates 

 actinal in position, separated from adambulacrals over most of ray 

 by a single series of actinal intermediate plates, and on disk by small 

 plates in transverse series; actinal interradial areas small; papulae 

 single in the small interspaces between abactinal plates; plates convex 

 and armed with a group of short, blunt, spinelets resembling para- 

 paxiUae or pseudopaxillse, 15 to 20 to a plate; marginal and actinal 

 spinulation compact; adambulacral plates small with slightly curved 

 furrow margin; spines small, crowded, grading into actinal spinu- 

 lation; proximaUy 5 or 6, distally 3 or 4 furrow spines, with 2 to 4 

 crowded series each of 2 or 3 subambulacral spines. WeU-developed
