sufficient number of specimens of the animal to justify me in bestowing upon it a 

 new specific name and added that East Indian specimens of species of this genus 



appear to be very rare. 



In my memoir on the crinoids of the coasts of Africa pubhshed m 1911, under 

 Tropiometra encrinus, new species, I gave a synonymy including Comatula sp., Audouin, 

 1817; Alecto encrinus Liitken, MS.; fAntedon, sp., Mosely, 1877, and MacMunn, 

 189o'; Antedon marmoraia P. H. Carpenter, 1888; and Antedon carinata (part) P. H. 

 Carpenter, 1888. The localities I gave as the "Red Sea," Aden, and ?Suez. I said 

 that this species ranges eastward to the South Sea Islands and the east coast of Asia; 

 it appears to be generally rare, though common about Ceylon (=indica). Under the 

 heading Remarks I said I was not absolutely certain that the Red Sea specimens of 

 Tropiometra should be referred to this species, as I had never been able to examine 

 any of large size, but they seem to be nearer encrinus of corresponding size than to 

 any other form. I added that Tropiometra encrinus, while having the same number 

 of ciirus segments as T. carinata and T. picta, has proportionately longer and stouter 

 ciiri, the stoutness being especially noticeable distaUy. Owing to the increased size 

 of the cirri as a whole, the proportions of the segments are the same as in T. picta. 

 There is no further mention of the characters of the new species. 



In my memoir on the Recent crinoids of AustraUa pubhshed in 1911 I said that 

 nothing whatever is known of the AustraUan range of Tropiometra encrinus. I in- 

 cluded it in the key to the Austrahan species of Tropiometra with the habitat Queens- 

 land (see p. 286). Under the heading Tropiometra encrinus I gave a reference to my 

 paper on African crinoids and followed this with the locahty East Indies, a locahty 

 not mentioned in that paper. This was the locahty of the specimen in the Copen- 

 hagen Museum with which the name Antedon encrinus was found, and which I re- 

 regarded as the type specimen. I said that this species is a smaller form than the 

 preceding (T. afra), the arms being rarely more than 120 mm. in length; each brachial 

 after those just at the base of the arms bears a pronounced median tubercle or keel in 

 its distal portion; the cirri have 20-25 segments; the color is mottled yellow and purple. 

 I remarked that there are no definite Austrahan records, but that I had examined a 

 number of specimens labeled "South Pacific" which possibly came from there. The 

 species occurs at Norfolk Island and apparently in the Marshall group. The locahty 

 Marshall Islands is an error for Kingsmill (or Gilbert) Islands. The specimens said 

 to be from the Gilbert Islands and the "South Pacific" are really from Rio de Janeiro, 

 Brazil, and represent T. picta. Nothing is known of the specimen said to be from 

 Norfolk Island. No species of Tropiometra is known from that region. In my re- 

 port on the crinoids collected by the Hamburg Southwest Austrahan Expedition pub- 

 lished in 1911 I included Tropiometra encrinus among the East Indian species occur- 

 ring on the coast of Austraha, without giving any definite localities. 



Dr. Clemens Hartlaub in his memoir on the comatuhds of the Blake collection 

 pubhshed in 1912 listed Java (?) among the locahties from which Antedon carinata is 

 known. This refers to the four specimens in the Hamburg Museum recorded by 

 Carpenter in 1882. The locahties Chile, Fiji (?), and Kingsmill Islands (?) given by 

 Hartlaub are based on data from mislabeled specimens of T. picta from Rio de Janeiro. 

 In a paper on the crinoids of the Hamburg Museum pubhshed in 1912, 1 said under 

 Tropiometra f encrinus that unfortimately I had overlooked the four specimens from
