more profusely spotted or blotched with yellow than is the 

 mainland form of this species. In examining series of speci- 

 mens one finds a few individuals from the mainland as heavily 

 spotted as some of the Farallon specimens, but the average 

 difference seems constant and the extremes are very dissimi- 

 lar. I therefore propose that the Farallon Island form be 

 called

Diagnosis. — Similar to Autodax lugubris Hallow, but yeHow spots more 

 numerous and often larger.

 February 8, 1899. 



Description of Type. — Head elongate, depressed, with truncate, protrud- 

 ing snout; nostril small, a little above and behind the corner of snout, with 

 groove running down to edge of lip, separated from its fellow and from orbit 

 by length of eye-slit; lip margin long and undulating; maxillary and mandibu- 

 lar teeth large; palatine teeth small, in series running back from each inner 

 nostril and forming a V-shaped figure; a large well-defined patch of para- 

 sphenoid teeth divided by a slight median groove and posterior notch; tongue 

 large, long, ovate, with a small posterior notch, free except along the median 

 line; neck short, somewhat constricted, a well-developed gular fold; body 

 subfusiform, diminishing toward both extremities; 13 transverse costal 

 grooves between limbs, extending from a short distance from vertebral line 

 entirely across belly; tail conical with similar transverse grooves; limbs well- 

 developed, posterior longer than anterior, toes overlapping when adpressed; 

 digits 4-5, well-developed, nearly free, with slight terminal disc-like expan- 

 sion; third finger longest, first short, second and fourth nearly equal; first 

 toe short, second and fifth and third and fourth nearly equal; skin every- 

 where smooth, but dotted with the mouths of small glands. 



Color above smoky seal-brown, lightest on the snout and limbs, dotted, 

 spotted and blotched with pale straw-yellow on top and sides of head, neck, 

 body, Hmbs and tail; largest blotches, on sides of neck, 2 by 4 millimetres. 

 Lower surfaces dirty yellowish white.
