BLOOD-VASCULAR SYSTEM OF THE LORICATI 29 
Family ScoRPANIDA. 
Sebastodes flavidus Ayres, yellow-tail rockcod; S. melanops 
Girard; S. mystinus J. & G., black fish; S. aurzculatus 
Girard, brown rockcod; S. carnatus J. & G., flesh-colored 
rockcod, and S. zedulosus Ayres, yellow-spotted rockcod. 
Family ANOPLOPOMATIDZ. 
Anoplopoma fimbria Pallas, black cod. 
Family HEXAGRAMMID. 
Hexagrammos decagrammus Pallas, sea trout and Ophzodon 
elongatus Girard, blue cod. 
Family CoTrTip. 
Scorpenichthys marmoratus Ayres, cabezon ; Calycilepidotus 
spinosus Ayres, and Hnophrys bison Girard. 
For detailed work, Ophzodon eclongatus was taken as a type. 
The reason for choosing Ophzodon was partly because of its 
position between the 2 extremes of the suborder, but espe- 
cially on account of its size (sometimes reaching a weight of 
70 lbs.), and the ease with which it can be injected. Every 
effort has been made toward accuracy. Several specimens of 
each species compared have been studied, in order to eliminate 
the error that might come from variation in different individuals 
of the same species. Notwithstanding, omissions, if not errors, 
have probably crept in. The drawings, rude as they may be, 
were all made from a single dissection, with the exception of 
Pl. I, fig. 1, which is a combination of several dissections. 
The material for this paper was collected by Chinese fisher- 
men at Monterey Bay, Cal. The work was done at Stanford 
University and at the Hopkins Seaside Laboratory, and under 
the direction of Prof. C. H. Gilbert, to whom I am indebted 
for many favors and the facilities for research. Also I am 
under the greatest obligations to Prof. G. C. Price, of Stanford 
University, for a room at the Hopkins Laboratory; and to Mr. 
J. C. Brown of the University of Minnesota, for-many favors.
