‘Mr. Coleman describes the redwood mealy-bug as Dactylopius 
seguoie, but, as Mr. Ehrhorn remarked to me, it is rather a Phena- 
Boceus, notwithstanding the 8-jointed antenne. It has certainly no 
affinity with the two species of Dactylopius it is said to most resemble. 
The description is very full, and includes all stages. T, D. A. C 
Fishes of Japan. — In the Proceedings of the United States National 
Museum (Vol. XXIII, pp. 739-769) Jordan and Snyder record the 
species of fishes collected in Japan by Mr. Pierre L. Jouy. These 
are eighty-three in number, six of them being new to science. These 
are Leuciscus jouyi, Apogon unicolor, Pomacentrus rathbuni, Aboma 
tsushime, Chasmias misakius, and Watasea sivicola. Chasmias is a 
new genus of gobies near Gillichthys, and Watasea a new brotulid 
near Neobythites. The new species are figured. I may here note 
that the name Chasmias is preoccupied by Chasmias Ashmead, a 
genus of Ichneumons, published a little earlier in the same proceed- 
ings. For the genus of fishes, Chasmichthys Jordan and Snyder 
may be substituted. 
In the same paper is given an identifi 
Japanese fishes collected by Dr. Thunberg and loosely described by 
Houttuyn in 1782. The adoption of Houttuyn's names necessitates 
several changes in nomenclature, among others the use of the name 
Scomber japonicus in place of Scomber colias, for the common chub 
mackerel. 
Jordan and Snyder have begun a series of monographic reviews of 
families of Japanese fishes. The first now published (Proceedings of 
the United States National Museum, Vol. XXII, pp. 725-734) 
includes the lancelets and lampreys, the second, the eels. In the 
ies are Branchiostoma nakagawe, 
cation of the species of 
script name of Dr. Hatta. 
In the review of the eels, fifty species are described, of which 
nineteen are new, all of these and some of the others being figured. 
The new genera are Xyrias, near Cirrhimurena, but without cirri, 
and /Emasia near Gymnothorax, but with the mouth bristling with 
large canines. ns51
