The preparation figured by Hartlaub certainly is not normal; possibly it had 

 become partially decalcified. 



Localities. Blake stations 34, 45, 101, 157; Investigator, Martinique; Albatross 

 stations 2327, 2319-2350; Caroline stations 43, 102; Atlantis stations 2999, 3303, 3465, 

 3478, 3482; "Caribbean Islands, 185-219 meters" (Blake stations 45 and 157) (Car- 

 penter). 



Geographical range. From the Yucatan Bank, southern Florida, and Cuba to 

 Martinique. 



Bathymetrical range. From 185 to 475 meters. 



Thermal range. One record, 16.53 C. 



Remarks. Dr. H. L. Clark said that the 15 specimens of granulifera secured by 

 the Atlantis were compared with Pourtales' type (M. C. Z., 267) and there is no doubt 

 of their identity. The only noticeable difference is that in the type the distal cirrus 

 segments are distally conspicuously wider than proximally, while in the Atlantis 

 material the projection of the lower (i. e., dorsal) distal margin is not so conspicuous. 

 But the Atlantis specimens show some diversity in this detail. The type has the 

 arms about 100 mm. long; several of the Atlantis specimens are larger, with arms 125- 

 150 mm. long. The type still retains a distinct dull purplish brown color, while the 

 Atlantis specimens are much more nearly white, especially when dry.

Description. The centrodorsal is thick-discoidal, the sides more or less convergent 

 distally, with the bare polar area 3-5 mm. in diameter and more or less tubercular. 

 The cirrus sockets are arranged in three very irregular marginal rows. 



The cirri are XX-XXIV, 18-20, from 30-40 mm. long, and moderately slender. 

 The first segment is very short, the second is longer, the third is longer than the second, 

 the fourth is rather more than twice as broad as long, and the remainder are approxi- 

 mately equal, nearly or quite half again as long as broad. The penultimate segment 

 is twice as long as broad, somewhat less in width than those preceding. The cirri are 

 slightly compressed in the distal half. The distal ends of the segments are slightly 

 enlarged, and in the distal third there is a slight enlargement of the distal dorsal edge. 

 The opposing spine is represented by a small blunt tubercle terminally situated and 

 directed obliquely forward. The terminal claw is short, about two-thirds as long as 

 the penultimate segment, stout and strongly curved. 



The ends of the basal rays are visible as rather large tubercles in the angles 

 of the calyx. 



The radials are entirely concealed, or at most form a gablelike ridge over the 

 ends of the basal rays. The IBr! are very short, chevron shaped or crescentic, 

 or entirely concealed. The IBr 2 (axillaries) are large, rhombic, from half again to twice 

 as broad as long; the edges all around are prominent, and there is a moderate rounded 

 median carination. The IIBr series are 2, with the first element very short and the 

 axillary about twice as broad as long and rhombic. The IIIBr series are 2, similar to
