tis, der Merstral, Tctractis, etc. All 5-rayed forms are grouped in 

 the second genus (quinqiieiidce), under which he mentions numerous 

 species or kinds, as das Fiinfeck Pentagonaster, das regulare Fiinf- 

 eck, Pciitayunastcr rcgularis, das gesternte Fiinfeck mit ausgerun- 

 deten Seiten, Pentagonaster scniihuiatus. 



Further, he says: "Der fiinfhornichte, Peiitaceros, hat fiinf tiefe, 

 ausgeschweifte Seiten, und lange, kolbichte oder zugespitzte Strah- 

 len. Die hierher gehorigen Arten sind entweder platt, plaiicc, oder 

 aber hockericht und bauchicht, gibbce." 



Then are mentioned: Der eingekerbte Fiinfstral Astropccteii, der 

 eingekerbte regulare Fiinfstral Astropecten regularis, der einge- 

 kerbte irregulare Fiinfstral Astropecten irregularis, der Gansefuss- 

 formige Pahnipes, der lederartige coriacea, die stumpfwinklichte 

 obtiisangnlcr, spitzwinklichte acutangulce, fiinf blattrichte pentape- 

 talce, die Meersonne Sol viarinis, die Sternhand Pentadactylus aster. 

 Besides those mentioned, there are numerous other single names 

 referring to starfishes and ophiurans. 



The absurdity of Schulze's names for other than historic purposes 

 is well exemplified in Pentadactylus aster, which is Linck's Pcnta- 

 dactylosastcr divided, possiby because it appeared too long. As a 

 recognizable description accompanies this name, those writers who 

 accept Pentaccros can hardly avoid adopting Pentadactylus also. 



Sherborn, who has given the weight of his authority in favor of 

 Schulze, misquotes in two instances in the ''Index Animalium." 

 Pahnipes Schulze [=Anseropoda Nardo] has, according to Sher- 

 born (1. c, 1151). the following species: coriacea, obtusangula 

 (sic), acutangula (sic), and pentapetala (sic). Schulze mentions 

 no names under his Palmipcs (p. 51). Those quoted by Sherborn 

 have nothing to do with Pahnipes, and, with one exception, are in- 

 rectly spelled in the bargain. Coriacea. for instance, is coordinate 

 with Palmipcs, and is a descriptive term ("der lederartige"). The 

 other names occur in the plural. So under Pentaccros Sherborn 

 cites "gibbus" and '^ planus." Schulze says : "Die . . . arten 

 sind entweder platt, plance, oder aber hochericht und bauchicht, 

 gibbce.'' 



These arc not specific terms, either in form or intent — that is. not 

 as we now employ specific names. But if Pentaccros "planer" were 

 taken as a binomial, equivalent to Pentaccros planus Linck (the type 

 of Pentaccros) . then Ilippastc'-ia Gray would become Pentaccros 

 and Orcaster would replace Pentaccros Gray, Sladen, ct al. .As a 

 matter of fact, Peiitaceros Schulze is not a genus, and if it were it 

 has no species name, being in the same class witli Pahnipes. Coriacea, 

 Tctractis, Hc.xactis, Hcptactis, Octactis, Enncaetis, Deeactis. Dode-
