Tule shrew

Sorex ornatus juncensis (English common name Tule Shrew ) is a probably extinct subspecies of the beautiful shrew ( Sorex ornatus ). She felt on the Baja California peninsula.

Features

The holotype, a young adult female, has a total length of 101 mm, a tail length of 41 mm and a Hinterfußlänge of 12.5 mm. The Condylobasallänge of the skull is 16.2 mm, the Basallänge 13.9 mm, the Mastoidbreite 7.5mm, the Palatallänge 7.2 mm and the interorbital width 3.5 mm. In comparison to the beautiful shrew the cranium is higher, narrower and less flattened. The tail is slightly longer and the feet are darker. The upper surface and the flanks of which are gray or darker. The underside is smoke gray with a hazelnut brown and wine - buff blurring. The tail is indistinctly bicolor, with a gray and brown wood colored top and a pale ocher - buff bottom.

Dissemination

Sorex ornatus juncensis was about 24.1 miles south of San Quintin endemic on the west coast of Baja California in the salt marshes of El Socorro.

Status

Sorex ornatus juncensis is known only from four specimens that were collected in September 1905 by Edward William Nelson and Edward Alphonso Goldman. Attempts by Laurence Markham Huey in the 1940s and by Jesús E. Maldonado in 1991 to rediscover this taxon remained inconclusive. Maldonado noted, moreover, that the salt marshes of El Socorro had largely dried up due to housing construction and that Sorex ornatus juncensis is probably extinct.
