OF JAPAN.

Of the Leland Stanford Junior Universitii. 
In the present paper is given an account of the species of Pedicu- 
lati, or Angler-lishes, known to inhabit the waters of Japan.. With 
other papers of this series it is based on the collections made by 
Messrs. Jordan and Snyder in 1900, under the auspices of the Hop- 
kins Seaside Laboratory of Leland Stanford Junior University, a 
duplicate series being deposited in the LTnited States National Museum, 
and upon specimens colle'cted b}" the United States Fish Commission 
steamer Alhatross.

THE PEDICULATE FISHES. 
Carpal bones notably elongate, forming a kind of arm (pseudobra- 
chium) which supports the broad pectoral. Gill opening reduced to a 
large or small foramen situated in or near the axil, more or less pos- 
terior to the pectorals. Ventral fins jugular if present; anterior dor- 
sal reduced to a few tentacle-like, isolated spines; soft dorsal and anal 
short; no scales. First verteljra united to cranium b}^ a suture; epi- 
otics united behind supraoccipital; elongate basal pectoral radii (acti- 
nosts. reduced in number; no interclavicles; post temporal broad, flat, 
simple; upper pharj'ngeals 2, similar, spatulate, with anterior stem 
and transverse blade; basis of cranium simple; no air duct to the swim 
bladder. Marine fishes, chiefly of the tropics and the oceanic abj^sses. 
The group is an ofl'shoot from the Acanthopteri, its chief modification 
being in the elongation of the actinosts and in the position of the gill 
opening. The Batrachoidida? are perhaps its nearest relatives.
