Three species, (Phyllotis Darwinii (2830) Coquimbo), (Mus pilosus (2831) Coquimbo), (Mus Olivaceus 2206 (2833) (2832)). — These three species from Pacific side of Andes: all distinct from those on Atlantic side. — But there are two species of same section Phyllotis in Patagonia (N.B. Phyllotis sub genus of Mus). The two other species of mice have close affinities with one from Patagonia & with two from Maldonado.

[38v]

In woods of Chiloe & Chonos Mus brachyotus (2432 & 2433) (perhaps two species) are allied to (2831) of Coquimbo [listed as Desmodus D'Orbingyi in Mammalia, pp. 1-3] & another (Mus obscurus of La Plata).

So that we thus have all (four) mice on West side different from East side.

five with swarm mouse.

Tierra del Fuego

Mus (1002) very flavitarsis [listed as Mus xanthorhinus in Mammalia, pp. 53-54] very close, if not same with (2035) from Patagonia [listed as Mus xanthopygus in Birds: 63-64]: also Mus magellanicus.

Patagonia including Bahia Blan

seven six species of mice

Phyllotis 2 species

Reithrodon 2 species (2032 cunicoloides) [listed as Reithrodon cuniculoïdes in Mammalia, pp. 69-71] (1755) xanthotis

N.B. Reithrodon is not found on Pampa of Cordillera.

N.B. Phyllotis not found in Plata: a friend of desert:

Maldonado eight species; one reithrodon distinct from Patagonian (1284 Reithrodon obscuriforus) [listed as Reithrodon typicus in Mammalia, pp. 71-72]

[38b] [r]

N.B.

There is a peculiar character to all mice of S. America, slightly different from true mice, Mr Waterhouse excepted one (1237) which oddly enough inhabited houses of Maldonado, but this appears rather different from English mice.

From New Holland Mr Waterhouse has two species, though unlike each other (one of mine from K. George Sound) — which has some considerable affinity with those but are different from those of all parts of Old World. (Mem: Opossums) (two specimens lately brought from Australia very like those from the Plata. —

None of my species identical with Rengger & Azara. Latter six all no doubt from further North.

Keeling Rat (3591) [listed as 3590]

(N.B. All the black rats same of same appear diseased— from top of mountain same)

differs from common rat in being smaller & brighter colour, rather yellower, no other difference, perhaps tail rather longer — belly instead of being white is yellowish.

Mr Waterhouse cannot make up his mind.

Ascension — 3901. Mus niger, ordinary fur longer than Europæan. & considerably softer, long silky hairs not so long, numerous or stiff. No whitish hairs, proportions different, rather less animal. — General colour black; deep grey beneath. [listed as Mus Rattus var.? insularis in Mammalia, pp. 35-37]

Mus (3902) Mus subniger, closely allied to last but sides & back intermixed with yellow hairs, under parts deep grey, feet black, proportions same as last, ordinary fur, not so long & harsher, more like common rat in fur.

Mice probably same, two specimens
