NO. 4 WILSON: PARASITIC COPEPODS 29 



Lepeophtheirus dissimulatus Wilson 

 Lepeophtheirus dissimulatus Wilson, Proc. U. S. Nat. Mus., vol. 28, p. 631, pi. 22. 



Seven females were taken from the skin of a yellow grouper, 

 Mycteroperca oljax (Jenyns); one female from a small mackerel; 

 one female from the gills of a second grouper, Cratinus agassizii 

 Steindachner; three females and a male from the skin of a third 

 grouper, Mycteroperca xenarcha, Jordan, all these four lots from 

 Albermarle Island. Eight females and four males from the skin of 

 a cabrilla, Paralabrax humeralis (Cuv. & Val,), at James Island. 

 This species came originally from the Galapagos Islands, but with 

 nothing to show its abundance. These new specimens from the same 

 locality but from five new hosts show that the parasite is well dis- 

 tributed among the groupers around the islands. 



ERGASILIDAE 



Artacolax saetiger Wilson 

 Artacolax saetiger Wilson, Proc. U. S. Nat. Mus. vol. 39, p. 361, pi. 51. 



A single female from the gills of a flying fish, Cypselurus callop- 

 terus (Giinther), at Charles Island. The species was founded upon 

 specimens obtained from a closely related flying fish at Woods Hole. 

 This record adds a new host and a widely removed locality, and is 

 the first to be made outside the original area.

BoMOLOCHus attenuatus Wilson 

 Bomolochus attenuatus Wilson, Proc. U. S. Nat. Mus., vol. 44, p. 198, pi. 21. 



One female from the gills of the ringed swellfish, Cheilichthys 

 annulatus, at San Francisco, Ecuador; two females washed from the 

 body cavity of a dredged Lophius at Bahia Honda, Panama; one fe- 

 male from the gills of a small Lophius-like fish at Port Utria, Co- 

 lombia. The species was originally found at Montego Bay, Jamaica, 

 so that the present record adds two new hosts and three new lo- 

 calities. 



DICHELESTHIIDAE 



Nemesis Pallida Wilson 



Nemesis pallida Wilson, Bull. 158, U. S. Nat. Mus., p. 464, pi. 33, figs. a-p. 



Two females from the gills of an unidentified shark at Bahia 

 Honda, Panama. This species is very common upon the large sharks 

 captured in the fish nets on Martha's Vineyard but these are the 

 first specimens to be reported outside of that locality.
