Hartlaub's determinations with the equivalents adopted herein are as follows: 

 Granulifera group:

Antedon granulifera=C. b. var. granulifera, and C. b. var. gemmata 

 Spinifera group: 



Antedon brevipinna— C. b. var. brevipinna 



Antedon brevipinna var. decora = C. b. var. insculpla 



Antedon brevipinna var. gracilis=C. b. var. gracilis 



Antedon brevipinna var. pulchra— C. b. var. pulchella, nov. 



Antedon brevipinna var. elegans=C. b. var. concinna 



Antedon brevipinna var. tuberosa=C. b. var. tuberosa 



Antedon brevipinna var. diadema=C. b. var. diadema 



Antedon brevipinna var. pourtal'esi—C. b. var. pourtalesi 



Antedon brevipinna var. laevis — C. b. var. laevis 



Antedon brevipinna var. spinosa=C. b. var. spinosa 



Antedon brevipinna var. coronala=C. b. var. coronala

Antedon brevipinna var. grannlosa=C. b. var. granulosa 



In 1914 Prof. Frank Wigglesworth Clarke and Dr. W. C. Wheeler published an 

 analysis of the inorganic components of the skeleton of this species (see pt. 2, p. 299, 

 Crinometra concinna). This information was republished in 1917 and 1922. 



In his report upon the Crinoidea collected by the Bahama Expedition from the 

 University of Iowa in 1893 Dr. Hubert Lyman Clark in April, 1918, recorded and gave 

 notes on Crinometra gracilis from station 2, and C. ornata from stations 9 and 16. 



In my report upon the unstalked crinoids of the Siboga expedition published in 

 1918 I listed all the forms referable to Crinometra under their original names, and said 

 that the species referred to by Hartlaub as Antedon angusticalyx P. H. Carpenter, 

 A. granulifera Pourtales, and A. pourtalesi P. H. Carpenter, as well as A. brevipinna 

 (Pourtales) belong in Crinometra. In my report upon the Crinoidea of the Danish 

 Ingolf Expedition I listed, as members of the genus Crinometra, C. brevipinna, C. 

 insculpta, C. granulijera, and C. gemmata and gave their ranges. In 1929 I recorded, 

 without comment, a specimen of Crinometra brevipinna from off St. Thomas, V. I., in 

 240 fathoms that had been presented to the British Museum by Capt. A. Morrell. 



In 1933 Prof. Torsten Gislen described and figured an interesting new form from Si . 

 Helena which he called Crinometra transversa, and in 1934 he discussed the brachial 

 structure of Crinometra concinna, G. gemmata, C. imbricata, C. insculpta, C. margaritacea, 

 C. pulchra, and C. transversa. 



Dr. Hubert Lyman Clark in 1941 recorded Crinometra granulifera, 0. insculpta, 

 and C. pulchra from various localities about Cuba where they had been dredged by the 

 oceanographic ship Atlantis, working under the joint auspices of the University of 

 Havana and Harvard University.
