Morris — Nomenclatural Authorlti/ for Gonionemiis miirbachii. 181 



Perkins, 1902 (loc. cit.), uses the binaiy niinie in the title of 

 his paper and describes morphological structures and illustrates 

 them with ten text figures, with probably sufficient detail to 

 establish the species. However, the species is undoubtedly 

 nomenclaturally established later, for Perkins, 1903 (loc. cit.), 

 €laborates and extends the facts of his previous paj^er, and gives 

 twenty-one text figures, of which nine duplicate those of his 

 earlier paper, and four plates with twenty-seven figures, of 

 which three are by the late W. K. Brooks, drawn at Woods 

 Holl in 1894, a year earlier than the discovery credited to 

 Murbach.

X Of tliis species, Mayer says, loc. cit. p. Itw, " It is more closely allied to the species 

 •described by Murbach [cites Murluicli, 1905, I. c] from Wood's Holl, Massachusetts, than 

 it is to Gonionemus vertens, A. Agassiz."
