The green turtle has been taken at Cape San Lucas. 

 It doubtless occurs in many places along the coast of the 

 peninsula. 



Chrysemys nebulosa, new species. Plates iv, v and vi. 



Pseudemys ornata. 



1883, True, Bull. U. S. Nat. Mus., No. 24, p. 33. 



Diagnosis. — Allied to C. ornata (Gray), but without 

 black centers in the costal ocelli, which are much more 

 irregular and indistinct than in that form. The markings 

 on the head, neck, and limbs, are much coarser, and the 

 longitudinal lines less numerous. There are four yellow 

 rays on the upper surface of the arm, instead of eleven. 



Type. — Cal. Acad. Sci. No. 2244, " Mainland abreast 

 of San Jose Island," Lower California,* W. E. Bryant. 



Description of the Type. — The neck is clove brown 

 with several pale longitudinal lines on each side. The 

 highest one of these ends on the temple in a large oval 

 spot of the same color. The lowest and largest is con- 

 tinued forward across the middle of the lower eyelid, 

 giving off, at the lower edge of the inferior maxillary 

 bone, a branch which, continuing forward, crosses to the 

 upper jaw, runs past the anterior edge of the orbit, turns 

 forward at a right angle, and terminates at the nostril. 

 The five similar lines on the nape are continued forward 

 over the top of the head, and, besides being more or less 

 undulating, give rise to several short transverse branches. 

 There are six longitudinal yellow rays on the forearm ; 

 one on each edge and two on each surface. Greenish 

 yellow lines traverse the backs of the five fingers and 

 four perfect toes. The vertebrals sometimes show black 

 spots. All the marginals are ornamented with black 

 ocelli. The plastron is marked with large longitudinal 



* Mr. Bryant informs me that the exact locality is Los Dolores, L. C, 

 and that No. 5245 was also taken there.
