Enrotylidce. Twenty-nine new species of this family were described, of 

 which ten were from the Philippine Islands, three from the Andaman 

 Islands, two from Assam, two from the Malay district, six from Africa, 

 and six from Peru. The species treated of belonged to the subfamilies 

 Encaustini and Dacnini, the author reserving the other subfamilies for a 

 future communication. 



Dr. Gwyn Jeffreys read the sixth part of his communications on the 

 Mollusca procured during the ' Lightning' and 'Porcupine' Expeditions. 

 This included an account of the specimens of the groups of Scissurella, 

 Trochus, Turbo, and part of Littorina, referable altogether to seventy 

 species. Four genera and twenty species were for the first time described 

 as new. 



A communication was read from Mr. H. 0. Forbes, describing a 

 species of scarlet Myzomela obtained in the island of Boeroe, one of the 

 Ceram group. 



Mr. G. A. Boulenger read a paper on the Geckos of New Caledonia. 

 The object of the author in preparing this paper was that it might serve 

 as a guide to the identification of the Geckotidce of New Caledonia, and at 

 the same time to bring the synonymy into order. To this end the author 

 had compared the typical specimens in the Museums of Brest, Lisbon, 

 Paris, and Brussels with those in the British Museum, and had given 

 short descriptions of every species taken from typical or well-authenticated 

 specimens. The number of species of Geckotidce actually known from New 

 Caledonia was fourteen : of these two were recorded for the first time, one 

 being new to science. — P. L. Sclatek, Secretary.
