6 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 40. 



possibly not quite the same as the East Indian species called by 

 those names by Carpenter. Thanks to the kindness of Mr. Chadwick 

 and Professor Herdman, I have been able to examine one of the 

 specimens identified as -4. serripinna, and I find it to be a new species 

 of Colobometra, and not an Oligometra at all. I also found in the 

 British Museum a specimen of what is undoubtedly his Antedon 

 parvicirra, which turned out to be a new species of Iridometra. 



In October 1909, Professor Bell reported upon the echinoderms of 

 the Percy Sladen Trust expedition, which included four crinoids. 

 All were misidentified. The four species are: 



Actinometra multiradiata = Comatella maculata. 



Antedon carinata = ? Cosmiometra gardineri. 



Antedon palmata = Stephanometra indica. 



Antedon spicata = Cenometra emendatrix. 



MATERIAL. 



The specimens examined in connection with the present work 

 include all the crinoids from Africa in the British Museum, the 

 Bergen Museum, the Museum of Comparative Zoology, the Copen- 

 hagen Museum, the Hamburg. Museum, the Museum fur Naturkunde 

 and the Museum fur Meereskunde, Berlin, the Oceanographic 

 Museum at Monaco, the Paris Museum, and the U. S. National 

 Museum. Among them are the originals of all the published records 

 of Leuckart, Guerin-Meneville, J. Muller, Michelin, Dujardin and 

 Hupe, von Martens, Wyville Thomson, Pourtales, Rathbun, E. A. 

 Smith, Bell, P. H. Carpenter, Hartlaub, and Ludwig, and most of 

 those of Doderlein and Chadwick. At Lyons Prof. R. Kcehler and 

 M. Vaney showed me the specimens collected by the Travailleur, the 

 Talisman, and the Princesse-Alice, upon which they are soon to 

 publish a report. Two of their new species I had already seen in the 

 museums at London and Paris, and I had drawn up diagnoses of 

 them; but it is only fair to those gentlemen to withhold my diagnoses 

 until they are able to publish theirs, and to confine myself, in treating 

 of the material collected by the French and Monacan ships, to the 

 published records. 



FAUNAL RELATIONSHIPS OF THE AFRICAN COASTS. 



There are known to-day from the coasts of Africa and the outlying 

 islands fifty- three species of recent crinoids; forty -five of these 

 belong to the Comatulida, representing seven families, viz ; the 

 ComasteridaB (six); the Himerometridre (twelve); the Colobome- 

 tridre (six) ; the Tropiometridse (three) ; the ThalassometridaB (eight) ; 

 the Antedonidse (eight), and the Pentametrocrinidae (two), while 

 eight are stalked, representing the Pentacrinitidse (one) ; the Hyocri- 

 nidse (one), and the Rhizocrinidse (six). These species are included 

 in twenty-four genera, of which four are stalked.
