Greater stripe-backed shrew
Sorex cylindricauda is a shrew of the genus Rotzahnspitzmäuse ( Sorex ). It comes in the People's Republic of China in several provinces in central China.
Features
With a head-body length of 6.7 to 7.7 centimeters Sorex cylindricauda one of the medium-sized shrew species. The cock reaches a length from 55 to 62 millimeters, and is almost as long, or at least 80%, only slightly shorter than the rest of the body. The hind foot 15 to 16 millimeters. The back fur is dark cinnamon brown, the abdomen gray-brown dark. On the back of a black band of the neck extends up to the rear body along the spine. It resembles S. caecutiens however, is somewhat larger.
The head has an overall length of 17 to 21 mm, the row of teeth of the upper jaw has a length of about 8.75 millimeters. Like most species of the genus has the kind in the maxilla per half an incisor ( incisor ) and then five unicuspid teeth, a Vorbackenzahn ( premolar ) and three molars ( Molar ). In the mandible, it has, however, a single canine ( canine ) behind the incisor. Overall, the animals thus have a dentition of 32 teeth. The roots of teeth are stained red as with most Rotzahnspitzmäusen. The first three -pointed teeth of the upper jaw are approximately the same size, the fourth and fifth are smaller and decrease gradually or are also equal. However, the fifth single pointed tooth is greater than at other Sorex species relative to the other teeth.
Dissemination

Way of life
Over the life of this kind are of the genus is little data as in many species. The habitat preferences of Sorex cylindricauda are unclear bedfordiae mainly based on regular confusion with the sympatric Sorex living; probably she prefers mountain forest areas, because these also surrounded the locality of the type specimen.
