On Scorpions dsc. from the Solomon Islands. 457 Blarina meridensis, sp. n. Size comparatively large, skull-length greater than in any member of the subgenus Gryptotis except B. magna, Men*. Colour darker, more sooty and less brown than in B. Thomasi, Merr., tlie only other South-American species. Tail much longer than in that species. Internal cusps to unicuspids indistinct, not definitely at the postero-internal angle of the tooth as in B. Thomasi. Back of large upper premolar not deeply excavated. Dimensions of the type (measured in skin) : — Head and body 79 millim. ; tail 37; hind foot, without claws 14, with claws 15*3. Skull : greatest length, including incisors, 23' 7 ; greatest breadth 11; tip of incisors to chief cusp of p.* 5'2. Hah. Merida, alt. 2165 m. Coll. S. Briceno. Type-. B. M. no. 98.5. 15.5. Dr. Merriam has shown that the members of this genus, like as they are in colour and general appearance, can be readily divided into species by their size, proportions, and the shapes of their premolars. In these respects none of the species in Dr. Merriam's monograph at all agree with B. meri-densis. Its only geographical ally, B. Thomasi, from Bogota, is readily distinguishable by its smaller size and shorter tail. LXXI. — Scorpions, Pedipalpi, and Spiders from the Solomon Islands. By B,. I. POCOCK, of the British Museum of Natural History. [Plate XIX.] Part of the material contained in the British Museum upon which this small contribution to the arachnology of the Solomon Islands is based was purchased from Mr. C. M. Woodford in 1887. A second instalment was procured by the officers of H.M.S. ' Penguin ' (Commander A. J. Balfour commanding), and was presented to the Trustees in 1894 and 1895 by the Lords of the Admiralty. In Thorell's tables of distribution of spiders occurring in the Austro-Malayan area (published in 1881 in vol. xvii. of the Ann. Mus. Genova) only one species of the order is recorded from the Solomon Islands. This is Argiope hougainvilla of Walckenaer. Walckenaer, however, mentions two more species, namely Ctenus marginatus and Nephila vitiensis, as doubtfully coming from this locality, and in the
