All the segments are longer than broad, except the basal three, and the fifth (or sixth) 

 is the longest. 



There are 23 arms of which two are very small. The longest exceed 100 mm. 

 Dr. Clark said that in their ornamentation the arms are more like Hartlaub's fig. 9, 

 pi. 5 (second specimen from Martinique) than they are like the figures he gives for 

 var. ornata (to which he referred the specimen), but he was not at all clear as to how 

 much weight slight differences of ornamentation properly carry in Crinometra. 



The difference between Hartlaub's Antedon brevipinna var. ornata and the second 

 specimen from Martinique (pi. 5, fig. 9) which he identified as Antedon granultfera is 

 not in the ornamentation, but in the character of the IIBr series — 2 in ornata, 4(3+4) 

 in granulifera. Dr. Clark does not mention the division series in his discussion. 



Dr. Clark said that the pinnules of the specimen in hand are remarkable for the 

 very great width of some of the basal segments. Thus P s is 6 mm. long with 10 seg- 

 ments of which the third is 0.75-0.80 mm. high and a trifle more than 1 mm. broad, 

 while the fourth is about as broad and is fully 1 mm. high; succeeding segments are 

 much narrower. 



He remarked that it will be at once noted that these pinnules are utterly different 

 from Hartlaub's fig. 6, pi. 4, but they are apparently identical with those shown in the 

 photograph, fig. 4, pi. 12. He said "No doubt Hartlaub has at least two distinct species 

 confused under his 'variety ornataV " Dr. Clark overlooked the fact that the genital 

 pinnules vary widely in shape according to the state of development of the gonads. 



He said that the arm fragments at hand (from station 9) agree perfectly in orna- 

 mentation and in pinnules with the whole specimen, and there is no doubt of their 

 identity.

 Antedon brevipinna var. coronata Hartlaub Mem. Mus. Comp. Zool., vol. 27, No. 4, 1912, p. 323 



(in key), p. 345 (description; Blake stations 219, 241, 272), pi. 11, fig. 7. 



Description. — Hartlaub said that a medium-sized specimen from Blake station 241 

 and another somewhat smaller but of similar habitus and of a similar reddish color from 

 Blake station 272 recall in the ornamentation of the lower brachials the first Martinique 

 specimen of granulifera (see page 330). But the agreement is not so close as in the case 

 of the specimen described as var. spinosa. In addition to these specimens Hartlaub 

 described as a representative of var. coronata a specimen deviating somewhat from those 

 from Blake station 219 that Carpenter had designated as pourtaUsi. 



In the specimen from Blake station 241 the centrodorsal is highly arched and 

 slightly flattened dorsally. Only a small, somewhat excavated, bare dorsal pole is 

 present. The interradial processes are well developed. In the specimen from Blake 

 station 272 the centrodorsal is flatter with a more pointed dorsal pole so that its form 

 approaches the conical, and the interradial processes are not so well developed.
