For detailed work, Ophiodon clongatus was taken as a type. 

 The reason for choosing Ophiodon 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 

 PI. I, fig. I, 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.
