A MONOGRAPH OF THE EXISTING CRINOIDS 691 



Gisle"n said that the young of the subgenus Comantk-us has, if his determination 

 is correct, a rather long unswollen anal cone and a tolerably lean disk. 



He concludes that naturally the fixed points obtainable by n examination of 

 the disk are only to be used together with the other chnracteiistics \\liich are found. 

 If, however, in the comparison and systematizing of the coinnstcriil young one takes 

 into consideration the appearance and formation of the disk, he believes that we shall 

 be able to predict with greater probability than otherwise to which species or genus 

 he young comasterid in question might be referred. 



UNIDENTIFIABLE SPECIES 



Locality. Albatross station 3809; off the southern coast of Oahu, Hawaiian 

 Islands; Honolulu Light bearing N. 2 E., 2.4 miles distant; 97-386 meters; bottom 

 temperature 8.72 C.; fine coral sand; March 27, 1902. 



Remarks. A number of comasterid pentacrinoids were dredged at this station, 

 some of which were attached to a cirrus probably of a species of Comactiniinae. 



This is the only record of a comasterid from the Hawaiian Islands, and is 

 especially interesting when considered in connection with the uncertain record of 

 Comatula Solaris from the Society Islands. 



COMATULA MONILIS. COMATULA POLYACTINIA, COMATULA MONILIFORMIS, COMATULA INSERTA, AND 



COMATULA ACTINODES 



Comatula monilis, C. polyactinia, C. moniliformis, C. inserta, C. aclinodes DUJARDIN and HUPE, 

 Hist. nat. dcs zoophytes, Echinodermes, 1862, p. 208. A. H. CLARK, Bull, du mus. d'hist. nat., 

 Paris, 1911, No. 4, pp. 245, 246 [polyadinis instead of polyactinia]; Crinoids of the Indian Ocean 

 1912, p. 283. 



MM. Dujardin and Hupe" listed these species as being contained in the collection 

 of the Paris Museum. The names are nomina nuda as given by them, and there are 

 no other references to them. 



During my visit to the Paris Museum in 1910 I made a careful search for these 

 names on the labels with the specimens, but was unable to find any of them, although 

 I did find several of the other names similarly mentioned by Dujardin and Hup6. 



COMATULA TRIQUETA 



Comatula triqueia (Liitken, MS.) VON GRAFF, Das Genus Myzosloma, 1877, pp. 12-16, 18, 22, 23, 72, 



79. KELLER, Das Leben des Meeres, Leipzig, 1895, p. 106. 

 Anledon triqueia VON GRAFF, Challenger Reports, Zoology, vol. 10, pt. 27, 1884, pp. 19, 32, 47, 48, 



54, 55 (Bohol, Philippines; myzostomes) . 



There is no clue to the identity of this form. Von Graff's first reference is to a 

 specimen brought by the Godeffroy Co. from the East Indies. His second reference 

 is to a specimen or specimens collected by Prof. Carl Semper and named by Carpenter. 



ACTINOMETRA. sp. 



Actinometra P. H. CARPENTER, Trans. Linn. Soc. (Zool.), ser. 2, vol. 2, pt. 1, December, 1879, p. 7. 

 Carpenter remarked that the foreign specimen dissected by de Blainville "would 

 seem to have been a true Actinometra [comasterid]."
