six in all. The five of these whose hosts are known are all parasites 

 on the genital apparatus, or the eyes of sharks. 



The other species which have from time to time been referred to 

 this genus must be transferred to the new genera, Lermieofodina 

 and Salmincola, or they prove to be synonyms. If the number left 

 in the original genus seems small while those transferred to other 

 genera is unduly large, we must remember that hitherto practically 

 no attention has been paid to the structure of the male. Further- 

 more, this genus with Olavella {AnchoreUa) , has for years served as 

 a dumping ground for such species as could not with certainty be 

 located anywhere else. And, finally, if we could select salmonea as 

 the type of Blainville's genus we could still retain the majority of 

 the species in the original genus. But Blainville never even saw a 

 specimen of salmonea, so that we are obliged to abide by the decision, 

 even thoagh it does cause so many changes. 



Accordingly we transfer to the new genus Salmincola the follow- 

 ing species, because they have no dorsal carapace, no free thorax 

 segment, no posterior processes, no palp on the first maxillae, while 

 the rami of the second antennae are unsegmented. L. alpinu, 01s-

L. Ucaudata Kr0yer, 1837, p. 275, pi. 3, fig. 11, is transferred to 

 the genus Charoinnus (see p. 656). 



L. clavigera Olsson, 1872, p. 63, pi. 5, figs. 1 to 6, is the same species 

 that had been described four years before by Kessler under the name 

 L. thymalli (see p. 613). 



L. cluthae T. Scott, 1900, p. 173, pi. 8, figs. 27 to 37, is shown by the 

 form and segmentation of the male to belong to the genus Charopinus 

 (see p. 654). 



L. coregoni Smith, 1874, p. 664, pi. 3, fig.l7, belongs to the genus 

 Aclitheres, as has already been shown on p. 623. 



L. coregonorum and L. ejtensa were established by Kessler in a paper 

 entitled Materials toward a Knowledge of the Onega Sea and the 

 District about it, particularly in its Zoological Aspects. They are 

 both described on p. 97 and figured on plate 4, figs. 1 and 2. After 

 a careful examination of these figures and a condensed description
