330 8PILOCALE. 



Gcnl. Char. White markings on back equaling the black area; 

 middle dorsal stripes continuous posteriorly with anterior transverse 

 stripes, which last are confluent with posterior transverse stripes; 

 under jaw straight or nearly so below; bullae large; mastoid capsules 

 inflated. 



Color. Black, with the usual style of white markings. In addi- 

 tion to the peculiarities mentioned among the general characters, 

 the following are added: Lumbar spots generally confluent with the 

 posterior transverse stripes. The tail spots are sometimes confluent 

 posteriorly, forming a narrow band across the base of the tail. No 

 white on thighs, and only rarely a few white hairs on the upper sur- 

 face of the foot. (Merriam.) 



Measurements. Total length, 400; hind foot, 45.

Type loealiiy. Grand Canon of the Colorado, Arizona. 



Geogr. Distr. Arizona. 



Genl. Char. Size medium. Skull broad and flat; fronto-parietal 

 region depressed. Postorbital constriction very great. 



Color. Pattern similar to other species of the genus in black 

 and white. External lateral stripe very large and broad, and broadly 

 confluent with the anterior transverse stripe, which in turn is some- 

 times narrowly confluent with the inner dorsal stripe. Exposed 

 white of tail occupies nearly the whole of the terminal half above and 

 the terminal two-thirds below. (Merriam, 1. c.) 



Measurements. Total length, 400; tail vertebrae, 142; pencil, 

 100; hind foot, 46. 



494. saxatilis. ySpilogale'), Merr., N. Am. Faun., No. 4, 189, p. 12. 



Type locality. Provo, Utah. 



Geogr. Distr. Utah. 



Genl. Char. Size large; tail longer than head and body; lateral 

 stripe nearly obsolete. 



Color. Black and white, similar in distribution to the general 

 style of the animals of this genus, with the following differences, as 

 indicated by its describer (1. c). External lateral stripe nearly obso- 

 lete, and barely or not continuous with anterior transverse stripe. 

 In the type none of the markings are confluent, but in another speci- 

 men the anterior transverse stripes and the caudal spots meet indis- 

 tinctly across the base of the tail. All other spots and markings are 

 distinct. 



Measurements. Total length, 450; tail vertebrae, 176; pencil, 

 100; hind foot, 49.
