A MONOGRAPH OF THE EXISTING CRINOIDS 289 



Java when examining the collections of that institution. I remarked that these prob- 

 ably belong to T. encrinus, though there is a possibility that they may be referable to 

 T. indica. At any rate they cannot belong either to T. picta or to T. carinata, or to 

 the larger forms of the T. afra group. In a paper on the crinoids of the BerHn Museum 

 pubhshed in 1912 I said that Tropiomeira encrinus, as given in my memoir on African 

 crinoids, is a composite including T. encrinus, T. audouini, new species, and T. indica, 

 new species. Under the heading Tropiometra encrinus I Hsted a specimen from eastern 

 Asia which I said was the type of the species, and one from the Indian Ocean, giving 

 notes on both. I also gave notes on a specimen labeled "?India" in the collection of 

 the Indian Museum. I said (under T. audouini) that T. encrinus has much larger 

 cirri than either T. audouini or T. indica, the cirri rcsembhng those of the American 

 T. picta in having comparatively long instead of short segments in the distal portion. 



In a paper on a small collection of crinoids from the Indian Ocean published in 

 1912 I recorded a specimen of Tropiometra encrinus from Sadras — ^an error for Madras. 

 In my memoir on the crinoids of the Indian Ocean pubhshed in 1912, under Tropio- 

 metra encrinus, I gave a synonymy including ?Alecto carinata Leach, 1815; Comatula, 

 sp., Audouin, 1817; fAntedon, sp., Moseley, 1877, and MacMunn, 1890; Alecto 

 encrinus Lutken, MS.; Antedon adeonae Bell, 1887; Antedon marmorata P. 11. Car- 

 penter, 1888; Tropiometra carinata (part) A. H. Clark, 1907; and 1909; and Tropio- 

 metra encrinus A. H. Clark, 1911. I recorded as encrinus 17 specimens from Galle, 

 Ceylon {= indica); 2 from Sadras (that is, Madras; =clarki); and 5 from ?India 

 {=clarki). Other records for T. encrinus listed were: East Indies; Muscat; Indian 

 Ocean; east coat of Asia; Java; Aden; Tor, Red Sea; Red Sea; Tuticorin, Madras 

 Presidency; Ceylon; Norfollv Island; and ?Suez. Only specimens from the first five 

 localities are clarki; those from the Red Sea are audouini, and those from Ceylon and 

 Tuticorin are indica. A typical specimen from eastern Asia (the one in the Berlin 

 Museum) was figured in lateral view. In 1913 I listed Tropiometra encrinus as an 

 East Indian species occurring in eastern Asia, and in my paper on the crinoids of west 

 Africa published in 1914 I said that T. encrinus is kno%vn from ?India, East Indies, and 

 Eastern Asia, and an undetermined species has also been recorded from ?Fiji, and from 

 the ?Kingsmill (=GLlbert) Islands. In 1915 I listed Tropiometra encrinus as a Malay- 

 an species occurring along the coasts of China and Japan, assuming that the specimen 

 labeled Eastern Asia was, like munerous other specimens of various species I had 

 examined with this label, from this region. 



Dr. Hubert Lyman Clark in 1915 recorded two characteristic specimens of 

 Tropiometra encrinus from Ceylon and included this species, together with T. indica, 

 in a list of the comatulids of that island. 



In the key to the species of the genus Tropiometra published in his report upon 

 the unstalked crinoids of the Siboga expedition in 1918 I included encrinus, giving as 

 the range the eastern coast of India and eastward to East Asia. In 1932 I gave a 

 detailed synonymy of Tropiometra encri/iu-sjand a detailed description of five speci- 

 mens from near Mandapam, with notes on specimens from Pamban Beach, Madras, 

 and Waltair, and figures. I gave the locahties from which T. encrinus is known as: 

 Eastern coast of India from Waltair south to Pamban Beach (Waltair; Madras; 

 Mandapam; Pamban Beach); Ceylon; Java; Norfolk Island; Fiji; Gilbert (Kings- 

 mill) Islands; Marshall Islands; and the Bonin Islands. Also recorded without
