a. No particulars (probably Jalor. — J. L. B.) 



I have no hesitation in referring this specimen to the species 

 which has lately been described by Mr. G-erritt S. Miller, jun. 

 It is allied to Mus jerdoni, but is easily recognizable by its 

 slightly larger size, slender form, and long tail with a whitish tip. 

 Mr. E. Evans, who procured the specimen, states that it was taken 

 in an absolutely dark cave, but when found was in too decomposed 

 a condition for satisfactory measurements to be taken. 



43. Mus ciliata, sp. n. (Plate LVI.) 



General colour above dark brown ; many of the hairs having 

 fawn tips, which, especially on the sides, give the animal a lighter 

 appearance. Underparts yellowish white, sharply marked off from 

 the colour of the back. The fur is of three kinds — (1) alight grey 

 underfur ; (2) fine soft hairs light at their bases with a fawn or 

 dark tip, the former colour being most abundant at the sides and 

 the latter on the back ; (3) long stiff spines, also light at their bases 

 but with a very dark tip. Ears moderately long, naked, and uni- 

 formly rounded. Hands and feet uniform dark sepia-brown above, 

 sometimes with an irregular longitudinal whitish stripe. Tail long, 

 unicolour, and covered with very short stiff bristles. Whiskers 

 very long and numerous ; the two supraorbital bristles especially 

 are longer than those in any other species except Mus edwardsi, 

 while there is also a long cheek-bristle on either side starting from 

 midway between the eye and the ear. 



The skull closely resembles that of M. vociferans, Miller, and in 

 a less degree that of M. sabanus. It differs from the former 

 in being slightly longer and of greater depth over the brain-case, 

 while the nasals are somewhat straighter. From the latter it 

 differs in the supraorbital ridges being much less prominent and 

 in the shape of the anteorbital foramen, which is narrower, espe- 

 cially at its upper end, caused by the maxillary plate being flatter, 

 i. e. less concave and nearer the rostrum at its upper end. The skull
