Clark — New Recent Crinoidsfrom the Indian Ocean. 85 



Color (in spirits). — Light brownish yellow with traces of a broad median 

 dorsal line of purple. 



Family FENTACRINITIDiE. 



Genus METACRINUS P. H. Carpenter. 



Metacrinus batheri sp. nov. 



Type. —Cat. No. -V!^, Indian JMnseum; Malay Archipelago; 160 

 fathoni.s. 



Stem stout, 7 mm. in diameter, strongly stellate in cro.ss section, with 

 the produced interradial angles l)roadly rounded instead of sharp; cirrus 

 sockets conHned to the nodals, transversely oblong, the shorter diameter 

 equal to the height of the nodals; nodals produced at the interradial 

 angles into high dorso-ventrally elongate tubercles, occupying their entire 

 lateral edges; internodals six or seven, alternating in size, the longer witii 

 the angles produced into dorso-ventrally elongate tuliercles resembling 

 those on the nodals, l)ut somewhat smaller; radial faces of internodals 

 with low broad rounded ridges, showing a tendency to l)reak up into 

 tubercles, between the produced interradial angles. 



Cirri 45 mm. to 50 mm. long (about seven times tbe diameter of the 

 stem) with forty -eight to fifty joints, the lirst four very short, sube(]ual, 

 the following increasing to the ninth which is nearly, or (piite, as long as 

 broad, then remaining similar for five or six joints and very gradually 

 decreasing in length distally, so that the later joints are about twice as 

 broad as long; cirri at first transversely oval in cross section, gradually 

 becoming round and after the first six or seven joints laterally Gompressed ; 

 on the terminal six or seven joints there are indications of a median 

 tubercle; terminal claw as long as the two preceding joints, conical, only 

 .slightly curved. 



Basals very prominent, shield shaped, in lateral apposition all aroimd 

 the calyx, strongly produced downward over the angles of the stem ; 

 radials narrow and band-like, of equal height all around the calyx, four 

 or five times as broad as long in the median line; i Br 4 ( 1 -}- 2) ; ii Br 

 five to eleven ( usually about seven ) ; arms dividing four or five times, with 

 usually one more axillary exteriorly than interiorly in reference to the 

 II Br series; arms as far as the iii Br axillary robust, the articular tuber- 

 cles rather strongly indicated, the dorsal surface perfectly smooth ; beyond 

 the III Br axillary the brachials have prominent finely spinous distal ends, 

 and are rough t(j the touch. 



The pinnules are essentially like those of 31. acutus. 



Color (in spirits). — White.
