to variations of other Hyclromediisae. In this comparison, speak- 

 ing of Hargitt's work, he noted " In Gonionenus [s/r] (G. 

 Murbachii) of Woods Holl, Massachusetts," etc., and in a 

 footnote says : " This species has been commonly called Gonione- 

 mus vertens, but it is quite different from G. vertens, A . Agassiz, 

 of the Gulf of Georgia. I propose for it the name of G. Mur- 

 bachii, in honor of its discoverer. Dr. Louis Murbach." 



H. F. Perkins, in June, 1902,* described " Budding in the 

 Larvae of Gonionema Marbaclui.''^ Perkins, again, in 1903 (^loc. 

 cit.), discusses "The Development of Gonionema Murbachii." 

 In this paper he notes "the first printed account of the Woods 

 Hole species of Gonionema," giving proper reference to Mur- 

 bach's paper of 1895. He then states that " It was not until 



1901 that the specific name Murbachii was bestowed upon it by 

 Dr. A. G. Mayer." The remainder of his paper takes up the 

 physiological and morphological characters in the development 

 of the individuals. 



Or again: 



Murbach, 1895 Ooc. cit.), evidently fixes the morphological 

 characters, which he discusses, under the binary name of Go- 

 nionemus vertens. 



Mayer, 1901 (loc. cit.), evidently intended to distinguish the 

 Woods Holl species from the Pacific Coast species named long 

 before by Agassiz, by the expression "(G. Murbachii)." How- 

 ever, there is no description of the species in connection with 

 this binomial. His footnote, as quoted above, refers to a dif- 

 ference in this species from G. vertens, and he properly indicates 

 the man in whose honor this species is named. He docs not, 

 however, give any reference to a previously published descrip- 

 tion; and it is not clear by the details of this record, nor of 

 Murbach 's own paper, that Dr. Murbach was the first ivide 

 infra) to collect the species at Woods Holl. As generally under- 

 stood, according to extant codes of nomenclature, this pul)lica- 

 tion of "(G. Murbachii)" is a nonien nudum.
