A MONOGRAPH OP THE EXISTING CRINOIDS 205 



1844 he himself visited the Paris Museum and the redescription of the species pub- 

 lished in 1849 was the result of his own personal studies. 



In Miiller's redescription of Comatula (Alecto) multiradiata published in 1849 he 

 gives the number of arms as 40-50 and the cirri as XXIV, 24-30. The specimens 

 upon which this redescription was based are: (l) The Linnean type at Lund; (2) 

 a dry specimen in the Paris Museum collected by P6ron and Lesueur which was also 

 mentioned under Comatula (Alecto) Jimbriata; (3) an alcoholic specimen from the 

 Moluccas in the Paris Museum collected by Pe"ron and Lesueur in 1803, with exactly 

 40 arms; and (4) an alcoholic specimen from the Moluccas in the Paris Museum 

 collected by Quoy and Gaimard with about 50 arms. These two last were both 

 included in Comatula multiradiata by Lamarck in 1816; they represent the species 

 now known as Capillaster sentosa. 



The description of Comatula Jimbriata published by Dujardin and Hupe" in 1862 

 is a translation of Miiller's redescription of 1843, the only change being that the 

 number of arms is given as 17-25. 



The authors add a note saying that Lamarck, who seems to have confused at 

 least two species, states that the arms, which are scarcely 81 mm. long, are more 

 slender than those of Comatula rotalaria, 12-30 in number, with the brachials slightly 

 spinous on the edge. 



Dujardin and Hupe"'s account of Actinometra multiradiata is a translation of 

 Miiller's description of 1843. No habitat is given for it. 



In 1874 Liitken, under the name of Actinometra gracilis, listed a specimen of 

 this species from Formosa (Taiwan). 



In 1875 Grube described as Comatula (Actinometra) borneensis a specimen from 

 North Borneo. 



P. H. Carpenter in 1876 and 1877 published notes on certain points in the 

 structure and anatomy of this form based on specimens which had been collected 

 by Semper in the Philippines, and in 1877 Prof. Ludwig von Graff described the 

 myzostomes from specimens in the Semper collection from Bohol in the Philippines. 



Carpenter visited the Paris Museum in 1876 and studied the specimens which 

 had been described by Lamarck and by Miiller. The results of this study he published 

 in 1879. He remarked, as had Miiller, that the dry specimen which had served 

 Lamarck as the type of Comatula Jimbriata and which had been brought from Australia 

 by Pe"ron and Lesueur was labeled Comatula multiradiata Lam., while Reynaud's 

 specimens he found bearing the name Comatula brevicirra Troschel and labeled as 

 having come from the Sunda Strait. He mentioned that he found the name 

 Comatula brevicirra associated also with the type of Comatula Solaris, with C. rotalaria, 

 and with some specimens of Comanthus parvidrra from Vavao. 



In 1882 Carpenter summarised the information on this species and published a 

 careful redescription of it. This redescription, however, was based upon 2 speci- 

 mens collected by the Challenger at Banda and upon notes taken at Paris on another 

 brought from the Moluccas by Quoy and Gaimard; all three of these belong to the 

 form now known as Capillaster sentosa. He mentioned some fragments of a dried 

 specimen from Sumatra in the Hamburg Museum, as well as Lamarck's type of 

 fimbriata at Paris and Linnets type of multiradiata at Lund, giving notes on all three.
