Clarl — Six New East Indian Crinoids. 81 



two and one half times as broad as Long, in the median line nearly twice 

 as long as the i 1 ► i- 1 ; the center, excepl at the anterior angle, is occupied 

 by a tubercle which is more elongated dorsoventrally than that on the 

 i E$n and, though as high, less prominent as it rises much less abruptly; 

 the lateral edges of the i Bri and i I'.r-j are turned outward, but not nearlj 

 so stronglyas is the case in G. lateralis; the lateral thirds of tin 1 proximal 

 edge of the axillaries and the corresponding portions of the distal edge of 

 i Bn are also turned upward to the same height as the lateral edges; the 

 eversion of the latter is most marked just, over the ends of the basal rays 

 and gradually decreases anteriorly to the distal corner of the lateral edge 

 of the axillary; it is continued thence along the sides of the first four 

 brachials; the inner lateral edges of the first live brachials are similarly 

 modified. 



The ten arms are, in the type, 105 mm. long.

Strotometra priamus sp. nov. 



The centrodorsal is very low hemispherical, almost discoidal, 1.5 mm. 

 to 2 mm. in diameter; the cirrus sockets are arranged in one and a partial 

 second marginal row, alternating and closely crowded. 



The cirri are xvn, 11-12, S mm. to 11 mm. long, slender, with elon- 

 gated segments; the first segment is very short, dorsally expanded into 

 a rounded knob-like process; the second is not quite so long as broad; 

 the third is twice as long as the median diameter ; the remainder are very 

 slightly shorter, becoming a trifle longer again, about two and one half 

 times as long as broad, on the antepenultimate and penultimate; the 

 penultimate is less in lateral diameter than the preceding; the third and 

 following are moderately constricted centrally with prominent distal ends, 

 this feature gradually decreasing distally; there are no dorsal processes; 

 the opposing spine is prominent, terminal, directed obliquely forward, 

 the proximal profile convex and the distal concave; the base occupies 

 only slightly more than one third of the dorsal surface of the penultimate 

 segment. 



The ends of the basal rays are visible as small hut prominent tubercles 

 in the angles of the calyx; the radials are concealed by the centrodorsal: 

 the i Bn are short, about four times as broad as long in the median line; 

 the proximal border is slightly convex, usually becoming straight in the 

 lateral quarters; the lateral edges of each t Bn make a considerable angle 

 with each other, but are in close apposition with those of the adjacent 

 i Br, ; they are turned outward and produced as in Gly/itometra lateralis; 

 the distal edge is sometimes obscurely scalloped in the lateral thirds, and 

 is slightly concave centrally for the receipt of a rounded posterior process 

 from the axillary; the axillaries are exceedingly short, aboul two and 

 one half times as broad as long: their lateral edges form a continuous line 

 with those of the I Bn and are about half as long as the latter; they are 

 similarly turned outward and produced, this feature continuing inward
