This species may be readily known from A', latifrons, its 

 nearest relative, by the possession of 2 or 3 buckler-like plates 

 below the suborbital ridge (where it is naked in the latter 

 species), by its having 6 rather than 7 or 8 anal rays, and by 

 its having a free fold posteriorly on the branchiostegal mem- 

 brane. But it is most readily known by the absence of a black 

 margin to the spinous dorsal posteriorly. In .Y. latifrons a black 

 margin is always present and conspicuous. 



Rhinogobius nicholsii (Bean) 

 A specimen taken in 50 fathoms of water. 



Porichthys notatus Girard 



The collection contains specimens taken at various depths 

 from very shallow water to 40 fathoms. 



Cryptotrema corallinum Gilbert 



A single specimen, 214 inches in length, taken at a depth of 

 50 fathoms. While the scales of the front part of the lateral 

 line are very prominent and slightly larger than those at each 

 side of them they are not nearly so much larger in proportion 

 as in larger specimens. 



Chilara taylori (Girard) 



A specimen 7 inches in length taken off Cerros Island in 40 

 fathoms of water. It does not show the usual spots. l)eing 

 uniformly light dusky above, shading to lighter on sides. 



Maynea californica Gilbert. (MS.) 

 Three specimens of this species without data, other than 

 locality, are in the collection from off La Jolla. The species is 

 known onl.y from the type (from off' San Nicholas Island) and 

 unpublished description by Dr. Gilbert. 



Two species from the north temperate Pacific have been 

 referred to this genus, but are now considered under the genus 

 Boihrocara, {B. pusilla [Bean], and B. mollis Bean). The 

 present species, however, differs from the type of the genus
