A MONOGRAPH OF THE EXISTING CRINOIDS 371 



?Vicinity of Perth, Western Australia; Hamburg Southwest Australian Expedi- 

 tion, 1905 [A. H. Clark, 1911, 1912; Hartmeyer, 1916] (1, H. M.). 



Endeavour; between Fremantle and Geraldton, Western Australia; 109-183 

 meters [A. H. Clark, 1914] (6, U. S. N. M., 35110; W. A. M.). 



Doubtful and erroneous localities. India [J. Miiller, 1841, 1843, 1849; Dujardin 

 and Hupe, 1862; Wyville Thomson, 1865; P. H. Carpenter, 1879, 1888; A. H. Clark, 

 1907, 1912, 1918]. 



North America (probably Western Australia) [J. Miiller, 1846, 1849; Dujardin 

 and Hupe, 1862; Verrill, 1866, 1867; Pourtales, 1869; P. H. Carpenter, 1879, 1883, 

 1888; BeU, 1882, 1884; A. H. Clark, 1907, 1911, 1912, 1918]. 



Geographical range. -From Annam, Misool, and Ceram southward to Port 

 Molle, Queensland, and to between Fremantle and Geraldton, Western Australia, 

 and westward to Billiton and the Sunda Straits. 



Bathymetrical range. From the shoreline down to 109 (?183) meters; most of 

 the records are from depths of not more than 20 meters. 



History. There can be no doubt but that the Alecto tessellata described by Prof. 

 Johannes Miiller in 1841 is the species under consideration, since the description fits 

 this form perfectly and does not apply to any other. The type specimen of Alecto 

 tessellata was presented to the Bamberg Museum by Johann Lucas Schonlein, who 

 was a celebrated physician born in Bamberg. It is labeled as having come from 

 India, which in those days was a very Indefinite geographical term. Schonlein never 

 visited India or the East Indies, and just how he acquired the specimen is not clear. 

 The type specimen of Alecto tessellata has not been reexamined since it was originally 

 described. In the Challenger report (1888) Dr. P. H. Carpenter especially mentioned 

 that it was the only comatulid given in the list of species included in that report that 

 he had not personally examined. 



In 1846 Miiller described Comatula (Alecto) milberti from a specimen presented to 

 the Paris Museum by M. Milbert, of New York, and labeled as having come from 

 North America. Jacques Gerard Milbert was a French painter and naturalist. In 

 1800 he accompanied, as chief artist, the French expedition in the corvettes Geographe 

 and Naturaliste sent out under Capt. Nicolas Baudin to explore the Australian seas. 

 Francois Peron was also a member of this expedition. Captain Baudin died at Mauri- 

 tius, and the Freycinet brothers succeeded him in command. In 1815 M. Milbert 

 came to America, where he spent seven years hi investigations in natural history, later 

 returning to Paris. One of our common northern butterflies, Vanessa milberti, is 

 named for him. It is most probable that Milbert collected the type specimen of 

 Comatula (Alecto) milberti on the coast of Western Australia and brought it with him 

 to New York. Therefore it is fairly safe to regard Western Australia as the type 

 locality of this species. 



On the same page and immediately following the description of Comatula (Alecto) 

 milberti, Miiller described Comatula jacquinoti, which was based upon a specimen in 

 the Paris Museum from Ceram labeled as having been collected by Hombron and 

 Jacqurnot, though Miiller mentioned only Jacquinot. Honore Jacquinot was a 

 French physician and a brother of Admiral Charles Hector Jacquinot. In the capacity 

 of ship's surgeon he had taken part in Dumont-d'Urville's expedition around the 

 world in the Zelee in 1837-1840.
