Cottus. H. Sauvage recognizes the following subdivisions of this 
genus : Cottus, Acanthocottus, Liocottus, Boreocottus, Porocottus ; and 
proposes the name of Elaphocottus to designate the species from Kamts- 
chatka and the Aleutian Islands, which, like C. pristilliger and claviger, 
have the praeopercular spines thick and antlered, and the head swollen 
posteriorly. He sketches the geographical distribution of the species cor- 
responding to the different subgenera, and gives diagnoses of C. cognatus, 
Rich., p. 142, viscosus, Haldem., p. 142, Gir., p. 143, and 
describes Cottus vietleri (Dyjpow.), p. 143, baikalensis (Dybow.), p. 144,

Triglopsis stimpsoni (Gill, MS.), Jordan, Man. Vert. 2nd ed., p. 256, Lake 
Michigan. [Prof. Jordan has informed the Recorder that this species = 
T. thompsoni ; also that he does not consider the division of Cottus into 
XJranided, Tauridea^ Potamocottus, and Triglopsis, as valid.] 
Platycephalus. This genus has hitherto been confined exclusively to 
the Red Sea, the Indian and Chinese Seas, and the Pacific ; H. Sauvage 
describes P. americanus, sp. n., p. 148, pi. ii. fig. 3, from the Potomac. 
He gives diagnoses also of P. vittatus, C. V., p. 149, bassensis, C. V., 
p. 150, grandispinis, C. V., p. 151, longiceps, 0. V., p. 151, and fuscuh, 
C. V., p’. 152 : N. Arch. Mus. (2) i. 
Platycephalus longiceps, C. V., is quite distinct from P. tentaculatus, 
Riipp., differing in the absence of tentacles, and the longer praeopercular 
spine. Id. 1. c. p. 151.
