Macrourus lepturus Gill & Towtisend. (Fig. 35.) 



The species is most closely related to .1/. acrolepis, but is unquestionably distinct. It differs from 

 acrolepis in the smaller eye, wider intcrorbital, longer maxillar)-, longer ventrals, more numerous rays 

 in the first dorsal, the more posterior position of the vent, and the thinner scales with lower less divergent 

 ridges and lower spines. 



First dorsal 11, 12; pectoral 22; ventral g. Orbit 4 to 4.33 in head; snout 3.66; intcrorbital width 

 4.5; length of maxillary 2.75; length of ventral i to 1.25; length of pectoral 1.75; length of second dorsal 



spine 1.33. 



Teeth small, in narrow bands, none of them strongly specialized, the outer series in upper jaw 

 ver>- slightly enlarged. 



Base of ventrals nearly midway between orbit and vent, the latter directly in advance of origin 

 of anal. First dorsal inserted over base of pectoral; interval bet%veen dorsals equaling two-thirds base 

 of first dorsal; second dorsal spine long, filamentous at tip, with 26 prickles, which begin a short dis- 

 tance above the base and become stronger distally.
