Chelipeds subequal, almost unarmed in the adult male; carpal spinules few and inconspicuous; chelae of moderate size, and fingers little gaping, as in riiricola. Legs broad, very rough; merus joints strongly serrulate above; propodal joints not much longer (on the upper edge) than their width; dactyli with six rows of spines. Color.—Greeff says: The color of the carapace in most of these crabs is a deep violet, but in some cases dark red; the sides are al- ways violet, the middle grayish-yellow

Chelipeds subequal, almost unarmed in the adult male; carpal spinules few and inconspicuous; chelae of moderate size, and fingers little gaping, as in riiricola. Legs broad, very rough; merus joints strongly serrulate above; propodal joints not much longer (on the upper edge) than their width; dactyli with six rows of spines. Color.—Greeff says: The color of the carapace in most of these crabs is a deep violet, but in some cases dark red; the sides are al- ways violet, the middle grayish-yellow. Chelae violet and also the bases of the legs; these become lighter toward the extremity, the dactyls being reddish-yellow with yellow spines. The color, however, varies in different individuals. Measurements.—Male (14869), length of carapace , width of same mm. Habitat.—Greeff says of the occurrence of (r. lagostoma at the islands of St. Thomas and Rolas, West Africa: From the forests of the coast region, their ordi- nary places of abode, they undertake excursions to- ward tlie interior of tlie islands and into the moun- tains. Here one meets with them in tlie open mucli more rarely than in the lowlands, but they occur also in holes in the earth, under stones, damp foliage, and rotten trees. They are without doubt very adept at climbing, as tliey were occasionally seen sitting high up in the trees. Range.—Trinidad, West Indies; Fernando de Noronha, Brazil. Also recorded from Australasia; Mauritius; Madagascar; ^ South and West Africa, including Ascension Island, South Trinidad Island, South Atlantic Ocean (Baylis), and from Bermuda with doubt. The writer has examined a subfossil specimen of a movable finger from the Bermudas. Material examined.— Trinidad, West Indies; Ensign Roger Welles, Jr., U. S. N.; 1 male (17603). Fernando de Noronha, Brazil; 1876-1877; R. Rathbun, Hartt Ex- plorations; 2 males, 2 females (40574). Ascension Island; March 21, 1890; W. H
