FISHES, ETC. OF THE “NASSAU” VOYAGE. 501: 
A single specimen of a Chondracanthus closely resembling C. merlucii in general form 
was taken in the mouth of a Gadoid fish, at the eastern entrance of the Strait.

- Specimens of this singular Crustacean, which I have figured of the natural size, were 
taken on the gills of fish at the entrance of the river Gallegos (east coast of Patagonia), 
and at the eastern entrance of the Strait of Magellan. It differs from the species (S. 
levigatus) on which the genus was founded, which was described by Quoy and Gaimard 
in the voyage of the Uranie (Zoologie, p. 541; Atlas, pl. 86. fig. 10) under the name 
of * Chondracanthe lisse," in the greater width of the sucking-disk and of the body, as 
well as in various other points, which will be readily understood by a comparison of the 
figures of the S. levigatus and the S. Kingi, which I have thus named because I believe 
that Captain King was the first to obtain specimens of it, as he makes reference in his 
narrative to remarkable Lernæans taken on fish at the entrance of the river Gallegos. 
In the determination of this species 1 have to express my obligations to Dr. Baird, who 
suggested to me its true affinities, to Prof. Kólliker, of Wurzburg, who informed me of 
_ the existence of other specimens of it in the Museum of the College of Surgeons, and to 
- Prof. Flower for his kindness in showing me the specimens in question.
