Lilljel;oi;g's seems, as far as I can judge, to exist no longer. There are, on the otlier hand, 

 paratype specimens both from Bohuslan and the west coast of Norway and Greenland. These 

 have been investigated by me and their identity with the form described by me above 

 verified. In addition I have investigated specimens caught at the type-locality of 

 Lilljeborg's species, near KuUaberg in Skelderviken; these investigations too confii'med 

 the above identification. 



It is, however, only the female of this species that W. LiLLJEBORG denotes by the name 

 of Cypridina globosa. The male is described afterwards under the name of PhUomedes longicornis 

 (p. 176). Which of these twu) names of species ought to be used? According to the Art. 28 c 

 in the International Rules for Zoological Nomenclature (Zool. Anzeiger, 1905), w^hich reads: 

 ,,Unter sonst gleichen Umstiinden ist derjenige Name vorzuziehen, der in der Veroffentlichung 

 an erster Stelle angefiihrt wird", I have taken globosa as the name for the species in this work. 



W. BaKD states in his work of 1860 a, p. 200 that the species Cypridina excisa de- 

 scribed by ^V. StIiMPSOX, 1853, p. 39 from Grand Manan is synonymous with his Cypridina 

 Brenda and supports this synonymization by a personal examination of Stimpson's specimens, 

 ,,fide specimens". ^^Tiether this statement proves that this form of Stimpsox's is identical 

 with the species described by me above is uncertain. The statements as to locale do not contra- 

 dict it; as wnll be seen below, I have found Ph. (Ph.) globosa common in Fortune Bay, New- 

 foundland, w^hich is a locale near Stimpsox's type-locale. Stimpsox's original description and 

 figure are unfortunately too incomplete to permit of a certain identification. This synonymi- 

 zation would, however, make it necessary to assume that this author had committed very 

 great mistakes in his reproduction of the shell and I have consequently considered it inconvenient 

 to adopt this view of Baird's. 



The chief reason why I — like a few preceding authors — have included Asterope groen- 

 landica, S. FISCHER, 1855 — a form that has been incompletely and certainly very incorrectly 

 described — as a synonym of the species dealt with here is that the very abundant Ostracod 

 material I have had an opportunity of investigating seemed to indicate that this was the only 

 species belonging to the family Cypridinidae that is found in Greenland — at any rate it is by 

 far the most abundant. It was first included in the genus dealt with here by G. 0. Sars, 1865, 

 p. 110, and G. S. Brady writes, 1868 b, p. 466 ,,and is either identical with, or closely allied to, 

 Bradycinetus Brenda''. In his Naples monograph G. AV. Muller writes of this species, that it 

 „vielleicht" is a synonym of Ph. (Ph.) globosa. 



The reason why A. M. NORMAX's PhUomedes lungicornis, 1867, p. 198 and 1869, p. 295 

 has not been included as a synonym is that this writer identifies this species of Lilljeborg's 

 with PhUomedes interpuncta (W. Baird). Normax, 1861, p. 280 also has a form Ph. longicornis: 

 it is clear, however, from his accompanying figure that it is Ph. interpuncta and not globosa 

 that was before the author on this occasion. 



Nor are Ph. lomjicornis in the older works of G. S. Bi; All^ (and I). R,OBERTSOX) included 

 in the list of synonvms given above. This writer seems also in the beginning not to have dis- 

 tinguished between Ph. globosa and interpuncta; cf. G. 8. P.i;\liN. 1880, p. 154, wliere these 

 two forms are synoiivmized.
