50 Mr. R. V. Chamberlin on new V. — New Chilopoda and Diplopoda from the East Indian Region. By Ralph V. Chamberlin, Museum of Com-parative Zoology, Cambridge, Mass., U.S.A. The new Cliilopods and Diplopods described in this paper were found in the course of the identification of several lots of specimens from the East Indies, making part of the collections of the Museum of Comparative Zoology. CHILOPODA. ScOLOPENDROMORPHA. Cryptopidse. Crypt ops brunneus, sp. n. With two sulci crossing the head longitudinally, these diverging more strongly near middle of length. The head is shorter and broader than in sulciceps, and does not so nearly cover the cervical sulcus of the first tergite. More widely separated from that species in having longitudinal sulci on the first tergite ; these extending forward and joining the cervical sulcus, not converging. From other species having the first tergite of this character it differs in having all the spiracles large and longitudinally elliptic. Prosternal margin convex on each side; marginal seta? 5 + 5. Ventral plates with a bowed transverse sulcus crossed by a much weaker longitudinal sulcus, which is often vague near the transverse one. Last ventral plate moderately narrowed caudad; caudal margin straight or slightly convex ; corners rounded. Coxopleurse caudally truncate ; pores larger than in sulciceps, but similarly removed by a wide space from dorsal plate and also from caudal margin .; without spines, bearing only finer setse. Hairs of legs much finer than in sulciceps. Colour, in general, brown, the head lighter, ferruginous. Length 16'5 mm. Locality. — Philippines : Luzon, Mt. Makiling (C. F. Baker). Type, Mus. Comp.
