486). In the description of the type the distance from the tip of 

 the snont to the ventrals is given at 33 hundredths of the length. 

 This is evidently a slip of the pen, and should read 43 hun- 

 dredths.

THE LITTLE LEOPARD SHARK. 



(Jordan and Evermann, 1896, I, p. 31.) 

 This shark is much more common in the summer than in the 

 winter in San Diego Bay. The following description was taken 

 from a specimen 23 inches in length. 



Head 6% in total length ; eye Ti/o in head, measured obliquely 

 across top of head from tip of snout to first gill opening ; carti- 

 lage of interorbital space 2i^ ; width of mouth 3 ; distance from 

 tip of snout to border of lip 31/5 ; distance from front of first 

 dorsal to front of second equal to the distance of first dorsal from 

 tip of snout, or contained 31/3 times in total length; distance from 

 base of second dorsal to tip of tail 3% in length ; dorsal slope of 

 caudal 4%. 



The ground color is gray or dove color, growing white below ; 

 a golden shade follows the middle of side. Back with broad black 

 cross-bars extending down to middle of sides about equal in wddth 

 to the interspaces. Narrower bars on top of head ; one on snout 

 following its contour; a straight one connecting eyes; one con- 

 necting posterior corners of eyes; a wider one at nape: a still 

 M'ider one, as wide as the succeeding ones, opposite insertion of 

 pectorals. One opposite inner posterior angle of pectorals; the 

 next under anterior third or dorsal, running up on fin nearly to 

 its edge, but not connecting with its opposite half. One under 

 posterior end of dorsal involving base of fin ; the next above base 

 of ventrals ; the next midway between the last and the succeeding 

 one, which is under the anterior end of second dorsal, meeting its 

 opposite half over the edge of fin. One under the posterior end 

 of second dorsal involving base of fin ; one opposite tip of anal, 

 and three equally spaced on upper edge of caudal. A series of 

 large spots along lower part of side anterior to ventrals, alter- 

 nating with the cross-bars. Posterior to the nape there is a spot 

 at the median dorsal line between each bar ; one of them at the
