merely as a substitute for Lamarck's 7nultiradiata. His idea was that, 

 two quite differeut species having been called inalfiradlata — one by 

 Lamarck" and one b}^ Goldfuss,'' but Lamarck's description being 

 quite worthless, whereas Goldfuss's is accompanied by an excellent 

 figure — the name should hold for the form with the recognizable 

 diagnosis, so he restricted it to Goldfuss's form. Subseciuently he ex- 

 amined Lamarck's original types, and from them drcAV up his diag- 

 nosis of midtifda. Now, thanks to Doctor Carpenter's investigations, 

 we know what Lamarck's m nit trad kita really is, and (as it is the 

 same as the Linnsean and lietzian Asterias innltlradiata) of course 

 the specific name miiltiradiata must be retained for it. Doctor Car- 

 penter realized this, but he resurrected viiiltifda for a specimen 

 which was among Lamarck's types, and differed both from the 7nul- 

 tlradlata of Lamai'ck and the m.ultiradiata of Goldfuss; but multijlda 

 is a pure synonym of midtivadtata Lamarck and can not be used for 

 any other species. The form may be renamed ConiaHter carpenteri. 



ISOCRINUS PARR^ (Gue'rin). 



In his monograph on the recent stalked crinoids, Doctor Carpenter 

 makes no mention of the species described as Eitciinus 'parrw by 

 Guerin in 1835.'' Guerin, under the heading Encrini/s, speaks of the 

 ^'Encrhius caput-medusce " described by Guettard and b}' Ellis 

 (^z=Isis asteria Linnanis), and then goes on to say that the '' Palma 

 animal" described and figured by Parra in 1787'* appears to repre- 

 sent another species. He describes this species in detail under the 

 name of Encriniis parra:'^ taking his description from Parra, and he 

 also reproduces Parra 's plate. P]xcept for the fact that the animal is 

 represented as growing on the seashore like a ])alm tree, the reproduc- 

 tion is very good. Doctor Carpenter mentions the reference to Parra 

 in his account of Isocrlmoi <(stci'ta^ but says he was unable to consult 

 it. Besides Guerin, Oken in 1815 and again in 1835 copied Parra's 

 figure, and Gervais refers to Encrinus ptti'ra'^ and it seems as if 

 one of the four must have been accessible to Doctor Carpenter. A 

 glance at Parra's figure shows that the species he had Avas the same 

 one which was described by Orsted in 1850 '' as Pentdcr'mus iniUlen; 

 the short internodes (four to six) and consequent crowding of the 

 cirri, combined with the stout stem, preclude the possibility of its 

 being any other West Indian species. There can, therefore, be but
