Les indications du tableau construit de cette manière ne sont pas 

 rigoureusement exactes, mais elles représentent des valeurs moyennes, 

 et qui correspondent aux conditions personnelles de l'observateur 

 (vision, distance de l'oeil, distance du papier etc.). En accompagnant 

 chaque dessin du seul et simple chiffre que l'on trouve dans son 

 tableau on sera compris par tout le monde , et l'on exprimera le gros- 

 sissement du dessin avec une approximation suffisante , certainement 

 préférable à l'exactitude prétendue des données jusqu'ici en usage.

19th March, 1895. — Lt.-Col. H. H. Go dwin- Aus t en, F.R.S., 

 F.Z.S., presented a paper on behalf of Mr. Walter E. Collinge, F.Z.S., and 

 himself, »On the Structure and Affinities of some New Species of Molluscs 

 from Borneo«. Three new species were described, viz. Damayantia Smithi, 

 Microparmarion Pollonerai , and M. Simrothi. Details were given of their 

 structure and comparisons instituted with other members of the genera and 

 allied Indian genera. One, perhaps, of the most interesting features was the 

 similarity they show anatomically to shell-bearing molluscs of Borneo. That 

 these slug-like forms of Borneo have the same close relationship to the shell- 

 bearing mollusca among whom they are now found living, as the Indian 

 forms bear to Macrochlamys and allied shell -bearing genera, there can be 

 little doubt, and any true attempt at classification must be based on these 

 lines, and would place a wide gulf between Girasia and Austenia on the one 

 side, and Parmarion and Microparmarmi on the other. — Mr. F. E. Bed- 

 dard, F.R.S., read a preliminary account of new species of Earthworms 

 belonging to the Hamburg Museum. These worms belong chiefly to the 

 genera Acanthodrilus and Microscolex ^ and had been collected in South Ame- 

 rica. — Prof. F. Jefi'rey Bell, F.Z.S., communicated, on behalf of Prof. 

 Alphonse Milne-Edwards, F.M.Z.S., Jardin des Plantes, Paris, the de- 

 scription of a new species of Crab of the genus Hyastenus^ obtained near the 

 Straits of Magellan during the »Challenger« Expedition, and proposed to be 

 described as H. consobrinus. — Dr. A. G. Butler gave an account of two 

 collections of Lepidoptera received by the British Museum. One from Zomba, 

 made by Mr. J. McClounie, remarkable for the number of specimens of the 

 fine Butterfly genus Charaxes it contained. The other made at Fwambo, 

 Lake Tanganyika, by Mr. Alexander Carson, interesting as including not 

 only rare species previously only received from Zomba and Lake Mweru, 

 but several novelties, the finest of which was Jimonia pavonina^ a new form 

 allied to /. artaxia. — Mr. P. Chalmers Mitchell. F.Z.S., read a paper in 

 which he gave a description of the proventricular crypts he had found in a 

 specimen of the African Tantalus {Pseudotantalus ibis) recently living in the 

 Society's Gardens. — P. L. Sclater, Secretary.
