Symphurus atricauda (Jordan and Gilbert) 



This rather common southern California species is represented 

 in the collection by a single specimen. A specimen taken some 

 years ago in the San Francisco market by Dr. Gilbert, and 

 another recently at Santa Cruz increases the northern range of 

 this species. It has hitherto not been recorded north of Point 

 Conception. 



From Symphurus leei, with which this species intermingles 

 in tropical waters, Symphurus atricauda may be distinguished 

 by its finer scales, having from 105 to 108 transverse series rather 

 than from 75 to 90, and in having a smaller head, which is con- 

 tained 4% to 51/3 times in the length of the body rather than 

 41/4 times. 



The following color-description wavS taken from a fresh speci- 

 men. The eyed side is greyish-brown with a series of 7 or 8 dark 

 brown cross bars at the bases of the dorsal and anal fins, but 

 fading out at the middle of the body. These become gradually 

 darker posteriorly, and are brownish-black on the tail. The fin 

 membranes are broadly edged with pale orange. The blind side 

 is colorless except the fins of the caudal region, which grow grad- 

 ually black posteriorly, and the visceral region, which is a deep 

 pink.
