PART 5 A MONOGRAPH OF THE EXISTING CRINOIDS 403 



and by Knight in 1867, while a specimen in the Paris Museum mentioned by Dujardin 

 and Hupe in 1862 and examined by myself in 1910 also bears it. 



For some years I have used this name in preference to eschrichtii which first ap- 

 peared 10 years later and was not formally established until 1841, both because it is 

 permissible, if not obligatory, under the accepted code to do so and in order to call 

 attention to the zoological work of those early explorers, Buchan and Franklin, with 

 whose material the name is found associated. 



In 1841 Prof. Johannes Muller, unaware of the previously published references to 

 this species, described in detail a specimen which he found in the Anatomical and Zoo- 

 logical Museum, Berlin, and which had been collected in Greenland by Prof. D. F. 

 Eschricht, calling the species Alecto eschrichtii. He had in the previous year mentioned 

 it under the name of Comatula eschrichtii, giving merely the distal intersyzygial interval. 

 In 1849 he published a revised description, calling it Comatula (Alecto) eschrichtii. 



In 1853 Mr. William Stimpson recorded this species from the island of Grand Manan 

 in the Bay of Fundy, in 45 meters. This record has been very widely noticed, but his 

 specimen was in reality an example of Hathrometra tenella as is shown by its size and 

 color. He mentions, however, an individual of this species from Greenland in the col- 

 lection of Prof. Louis Agassiz which is probably the one referred to by Mrs. E. C. and 

 Mr. Alexander Agassiz in 1865 and 1871. 



In 1857 Prof. Christian Liitken recorded it, under the name of Alecto eschrichtii 

 from Pr0ven, Greenland, where it had been found by Pastor J0rgensen in 36 meters. 

 To him belongs the credit of identifying with Muller's Alecto eschrichtii the Asterias 

 pectinata of Phipps, Scoresby and Dewhurst; but he seems never to have come across 

 the references to the name glacialis. 



In 1860 Walker recorded this species as Alecto glacialis from the collections made 

 by the Fox in 1857, his final memoir appearing in 1875. 



In 1865 Mrs. E. C. and Mr. Alexander Agassiz mentioned the occurrence of this 

 species in Greenland in 274 meters, a new depth record and therefore a record based 

 upon previously unnoticed material. The specimens to which reference is made are 

 undoubtedly those numbered 282 in the collection of the Museum of Comparative 

 Zoology, and apparently also those numbered 54. These were given to the Museum by 

 Prof. Louis Agassiz in 1863, but there is no evidence as to how he obtained them. Some 

 others in the collection (281) were purchased from Salmin of Hamburg in 1859. There 

 is a possibility that the lot numbered 54 was collected by Dr. Hayes on the schooner 

 United States, which left Boston on July 10, 1860, and returned on October 23, 1861. 

 Dr. Hayes was already familiar with work in the Arctic, for he had previously served 

 with Dr. Kane in the Advance, which, together with the Rescue, was sent out by Mr. 

 Grinnel in search of Franklin. 



Some of the specimens from "Greenland" in the British Museum may have been 

 collected by Dr. Kobert Brown and Mr. Edward Whymper near Disco in 1867. 



In 1870 Th. Jarzynsky published a preliminary catalogue of the animal life on the 

 Murman coast in which he included "Alecto sarsii" and "Alecto, sp.," both of which 

 he gave from the Arctic seas and the western region of the Murman littoral, the Motka, 

 Kola, Ura, Ara and Litza fjords. I have no doubt whatever that both of these names 

 refer to this species. In the Kola Fjord very small specimens with about 20 cirrus seg- 

 ments are common, and these are unquestionably Jarzynsky's sarsii; the unnamed form 

 was probably based on larger individuals, which in general appearance are more or less
