RESULTS FROM MAMMAL SURVEY. 49- 



2. IE. norvegicus, Brxleben (i.e., B. decumcmus, Pallas) as visitors. 

 brought from Europe on shipping and found sparingly in Seaports,, 

 and especially in Dockyards. 



3. JE. nemoralis, Blyth, representing the E. rufescens, Gray, of 

 the Mainland, distributed sparsely as a tree rat all over the Island, 

 up to 1,500 feet altitude. 



4. JS. Tvandianus, Kelaart, representing the " White bellied 

 variety " of ^. rufescens. This is the common house rat of the 

 whole Island from the sea coast up to the highest altitudes. 



5. JE. helaarti, sp. n. Perhaps most nearly related to E. nitidiis 

 of the Himalayas, as surmised by Kelaart. A highland form, only 

 found at elevations of 5,000-6,000 feet. 



The three indigenous species may be distinguished as follows : — 



A. Hair comparatively short. 



a. Underparts ... ... ...nemoralis, Blyth. 



h. Underparts pure white ...Tiandianits, Kelaart. 



B. Hair comparatively long, under- 



parts dirty white, the individual 



hairs with slaty bases ... . . .lislaarti, n. sp. 



G. — A Second Species of Gcelomys from Ceylon.

During the preparation of the general list of the Singhalese 

 Mammalia collected by Major Mayor, the skin recorded in the 

 preliminary list of his first collection as " Leggada hannyngtoni " 

 has been re-examined, and proves to represent a second species of 

 the recently described genus Gcelomys. It has, indeed, a very con- 

 siderable resemblance to the Coorg Leggad, and the accident that 

 its hindfoot was wrongly recorded as 22 mm., just as in the Leggad, 

 in place of its true measurement, 25 mm., was no doubt largely 

 responsible for the mistake. 



The species may be called : — 



Gcelomys bicolor, sp. n. 



Size, perhaps, averaging slightly less than in G. mayori. Fur 

 much more strongly spinous than in that species, the spines 10 — 11 

 mm. in length by about 0.4 mm. in breadth. General colour above, 

 lighter than in G. mayori owing to the ends of the wool hairs being 

 of a lighter buff, but on the posterior back the colour is darker, 

 from the predominance of the black-tipped spines. Sides clearer 

 grey. Under surface from chin to anus wholly sharply-defined 

 snowy white, the hairs white to their bases ; the white ascending
