SOREX. 55 
Dr. Coues remarks that this subgenus is related to the European Crocidura ; and, from 
his descriptions, I should hardly suppose it to be separable. In any case the absent 
unicuspids are probably the fourth incisor and the premolar, as Dr. Brandt has shown 
to be the case in Crocidura. | 
As far as we yet know, each of these subgenera is represented within our limits by 
a single species. These may be easily distinguished by the following characters :— 
1. S. vere-pacis. Teeth 32. Uniform dark dusky brown, hardly lighter beneath. 
Length about 3!-40, of tail 2-00. 
2. 8. evotis. Teeth 28. ‘Hoary brownish cinereous above, ashy-grey beneath.” 
Length 2”-90, of tail 0-90. 
1. Sorex versx-pacis. (Tab. V. fig. 1.) 
Corsira temlyas, Gray, P. Z.S. 1848, p. 79 (sine descr.)". 
Corsira teculyas, Gray, MS. (in Mus. Brit.)’. 
Sorex vere-pacis, Alston, P. Z.S. 1877, p. 445 (descr. orig.)’. 
Hab. Guatemata, Coban (Mus. Brit.). 
In 1843 the late Dr. Gray named, without any description, a number of Mammals 
obtained by the British Museum from Vera Paz, Guatemala, and purchased, I believe, 
from Mr. Leadbeater. Among these were two large dark long-tailed Shrews, on which 
Gray bestowed the barbarous title temlyas 1, afterwards altered on the Museum labels 
to teculyas. By the kindness of Dr. Gimther I was enabled to have the skull of 
one of these specimens extracted, and was thus able to show that it belonged to 
restricted Sorex with thirty-two teeth, the form and proportions of which bear a con- 
siderable resemblance to those of the European S. minutus. I have hitherto met with 
no other examples of this Shrew than Gray’s types; and it therefore appears probable 
that the species is not common in Guatemala. 
92. Sorex evotis. 
Sorex (Notiosorex) evotis, Coues, Bull. U.S. Geol. & Geogr. Surv. il. p. 652 (1877, descr. orig.)’. 
Hab. Mexico, Mazatlan (Bischoff, U.S. Nat. Mus."). 
According to Dr. Coues this species is nearly allied to S. crawfordi, Baird (which 
inhabits New Mexico), but differs not only in colour but in its much larger size and 
proportionally shorter tail. ‘The coloration is very nearly that of some specimens of 
Crocidura leucodon, but rather more cinereous above and less distinctly bicolor” 1, 
The still unique types of both 8S. crawfordi and S. evotis are in the National Museum 
at Washington.
