WEST INDIAN STARFISHES 127 



station 238, in 127 fathoms, off Camman. It may be identical 

 with. C echinulatus Per., as now understood by me. It is per- 

 haps the form figured by Perrier (1884) on pi. x, fig. 2. 



Ludwig (op. cit., p. 455, 1910) considered 0. mirahilis the 

 young of coronutiis and erroneously adopted the latter name. 

 The name mirabilis has three years of priority. Moreover the 

 type specimen of mwahiUs was larger than that of coronatus, 

 Perrier, 1894, kept the two as distinct species, though he dis- 

 placed the names and put his former types of coronatus with 

 that of 7nirabilis. 



With only the records given by Perrier, it is not possible to 

 give accurately the distribution of this species in the Blake 

 dredgings, separately from the other forms compared with it by 

 him, in 1884, for in most cases he gives no information even as 

 to the presence of spines on the disk. The following stations, 

 however, are valid for this form : 



Station 148, off St. Kitts, in 208 fathoms, fine sand; station 

 238, off Grenadines, in 126 fathoms, coral sand; station 264, off 

 Grenada, in 416 fathoms, gray ooze ; station 291 in 200 fathoms, 

 off Barbados. Most of the above have been confiraied by exam- 

 inations of the specimens. 



It was also taken by the Albatross at a number of stations, in 

 similar depths. The Bahama Expedition dredged specimens at 

 station 2, off Havana, in 210 fathoms.

Cheiraster coronatus Perrier (pars), 1894, pp. 271, 275 (not the form then 

 described).

The type of this species, as originally described by Perrier, in 

 1884 (p. 262) was from Blake station 2, in 805 fathoms. Its 

 characters, which were given briefly, are as follows : 



Radii 8°^°^ and 65™°^; ratio, 1:8.1. Superomarginal plates 43. 

 The rays are slender and long, with the interradial angles 

 scarcely rounded. 



The superomarginal plates are longer than broad, angles 

 rounded; each bears one median marginal spine; that of the
