Apparently closely allied to Maynea patagonica, but less robust, 

 with sharper more -tapering snout, more posterior insertion of dorsal 

 fin, longer pectoral fin and wider gill-slits. In M. patagonica, the 

 dorsal fin has its origin in advance of the base of the pectoral; the 

 pectoral fin is short, less than one-third the distance between pectoral 

 base and origin of anal fin; and the gill-slit extends only to a point 

 just below the middle of the pectoral base. 1 M. patagonica also is 

 said to have developed pseudobranchiae. 



Maynea buTbiceps Garman is apparently without pores on sides of 

 head. The figure of the type represents the fin rays as simple, but 

 in a note kindly communicated to me by Mr. Garman, I am informed 

 that they are not simple, the median pectoral rays being thrice 

 divided. Gymnelis conorhynchus Garman should apparently be 

 referred to Maynea rather than to Gymnelis, the latter being character- 

 ized by the entire absence of scales. M. conorhynchus seems to have 

 no pores on head, the dorsal and anal fins have less numerous rays, 

 while the rays of the pectoral are more numerous than in 

 M. californica; also, the suborbital ridge is swollen and prominent, 

 making the mouth appear inferior. In other respects it appears 

 closely related to M. californica. 



LYCOGRAMMA, new genus {Zoartidae). 



A deep-sea Lycodid, without ventral fins, with wide gill-slits con- 

 tinued well forward under the throat, the two narrowly separated 

 anteriorly; the bones of head deeply channeled for sensory canals; 

 the body scaled; the lateral lines distinct, two in number, the anterior 

 running high on sides, parallel with the back, discontinued at a point 

 about one orbital diameter behind the vent; the posterior line be- 

 ginning below and slightly in advance of this point and running 

 along middle of sides to the tail. 



Type of the genus. — Maynea brunnea Bean.
