By FRANK M. CHAPMAN.

Scalops aquaticus australis, subsp. nov. Char. Subsp.-Similar to Scalops aquaticus, but averaging slightly browner and constantly much smaller. Description of Type (Coll. Am. Mus. Nat. Hist., No. -916, Gainesville, Florida, May 4, I89I; F. M. Chapman).-Pelage soft and full, silvery grayish brown; upper surface of fore feet and hind feet very scantily covered with short whitish hairs; tail with a few longer grayish hairs. AMeasuremnents.-From the fresh specimen, total length, I48 mm.; hind foot, 17; tail, 22. While the characters which distinguish this race are to be found mainly in its small size, they are too striking to be ignored. Of the five specimens of austr-alis in the American Museum Collec- tion only two were measured in the flesh; the remaining three are, however, evidently quite as small. The flesh measurements of the two specimens compared with those of five specimens of S. aquaticits from the vicinity of New York City are as follows:

Sitomys niveiventris subgriseus, subsp. nov. Char. Subsp.-Similar to Sitomys niveiventris, but smaller, darker, and with the hairs of the underparts plumbeous at the base. Description of Type (Coll. Am. Mus. Nat. Hist., No. 74 5 adult male, Gainesville, Florida, January 30, I889; F. M. Chapman).-Above between wood-brown and cinnamon,1 very sharply defined from the under surface, clearer about the face and sides, mixed with blackish on the back, forming an indis- tinctly defined darker, median dorsal area; underparts, including the feet, white, the hairs basally plumbeous ; whiskers rather scanty; ears proportionally rather large, both surfaces finely covered with short, silvery white hairs ; tail short, bicolor, very sparsely haired and without an appreciable pencil; soles of the hind feet naked, except at the heel, which, with the tibke for a space of 4 mm. from the heel and the upper surface of both front and hind feet, is thinly covered with short hairs. Measurements.-From the fresh specimen, total length, 122 mm; tail vertebroe, 45. From the skin, hind foot, I6.5 ; height of ear at anterior base, i3; height from crown, 9; greatest width, 9. The female resembles the male both in color and size ; young specimens are smoke-gray above somewhat darker dorsally and with a buffy tinge about the nose. Beyond having a shorter and relatively broader skull than S. niveiventris this new form apparently does not differ cranially from that species. The differences in size are shown by the following measurements. Average of three males and three females of S. niveiventris, measured in the flesh: total length, 142 mm. ; tail vertebrle, 52. Average of seven males and seven females of S. n. subgriseus: total length, 123 mm.; tail vertebrae, 43. Cranial measurements from the same specimens are:

This little mouse is exceedingly common in the vicinity of Gainesville. It inhabits cleared fields, particularly thocse which are under cultivation, cornfields being among its favorite haunts. It lives in holes in the ground, and so far as I observed does not

Signs of its presence are therefore readily observable, and traps set at the mouths of its burrows will generally catch several individuals. A female taken January 30, I889, contained three half-grown embryos. The haunts of this species and of Sitomys americanus gossypinus were as sharply defined as were the wooded or cleared areas. The latter was never found in perfectly cleared fields, while the former did not occur in wooded tracts. In the 'deadenings,' however, where the trees are killed by girdling, and the crops are planted beneath them, both species were found together, subgriseus living in its underground retreats, while gossypinus occupied hollow trees or decaying logs. This difference in haunts is paralleled by the local distribution of Sitomys niveiventris and S. a. goss,ipinus on the east peninsula of Indian River. There niveiventiis is confined to the immediate vicinity of the beach where the only growth is the low, scrub palmetto (Chamaerops serrulata). In ground of this nature gossy- pinaus is rare or wanting, but as one goes inland the palmetto gradually gives way to live oak, and at the same time gossypinus replaces niveivent-is. The paler coloration of niveiventris as compared with su4griseus is thus presumably due to the nature of its haunts. Sitomnys niveiventris and its representative interior race S. n. subgrisems, bear no close relationship to any known member of the genus to which they belong. With the exception of the diminutive Sitomys taylori (Thomas) of Southern Texas they are the smallest members of the genus which have thus far been described. As compared with Sitomys americanus, their promi- nent external characters, aside from color, are their smaller size, relatively shorter tail and longer hind feet, and shorter pelage. Cranial differences are apparently to be found only in size and proportions. S. niveiventris and S. n. subgriseus have a relatively broader sktull than has S. americanus, and the brain-case is more depressed posteriorly; the ascending arch of the maxillary is actually as wide as that of S. americanus, and therefore is relatively wider.
