genus Lophoynathus, and the other a snake of the Indian genus Simotes, 

 proposed to be named respectively L. maculilabris and S. Forbesii. The 

 snake was of special interest, as no species of the genus Simotes had hitherto 

 been previously known to occur eastward of Java. 



June 19, 1883. — Prof. Flower, LL.D., F.K.S., President, in the chair. 



The Secretary read a report on the additions that had been made to the 

 Society's Menagerie during the mouth of May, and called special attention 

 to a fine example of the Surucucu or Bush-master Snake of South America, 

 Lachesis mutus, presented by Mr. H. Y. Barkley, of Pemambuco, on the 

 22nd of May. 



The Secretary read an extract from a letter received from Mr. Albert 

 A. C. Le Souef, containing observations on the coloration of the plumage 

 of the Satin Bower-bird, Ptilonorhynchus holosericeus. 



Prof. E. Ray Lankeeter read a memoir on the muscular and endoskeletal 

 systems of Limulus and Scorpio, drawn up by himself with the assistance 

 of his two pupils, Mr. W. J. Barham and Miss E. M. Beck. These 

 investigations seem to confirm Prof. Lankcster's previously expressed views 

 as to the near affinity of these two forms, hitherto usually referred to 

 different classes of the Animal Kingdom, and to justify the association of 

 Limulus with the Arachnida. 



A paper was read by Dr. Gwyn Jeffreys, on the Mollusca procured 

 during the cruise of H.M.S. ' Triton' between the Hebrides and Faroes in 

 1882. Ten new species of Gastropoda were described, and another species 

 (Fusus Sabini) was fully diagnosed. The chief interest of the paper 

 consisted in the distinction of the Mollusca inhabiting the "warm" and 

 "cold" areas of that sea-bed, in accordance with the views of Dr. Carpenter 

 and the late Sir Wyville Thomson. 



A communication was read from Mr. Martin Jacoby, containing 

 descriptions of some new species of Beetles belonging to the family 

 Galerucidcc. 



Prof. P. Martin Duncan read a paper on the Madreporarian genus 

 Phymastrcca of Milne-Edwards and Jules Haime, and gave the description 

 of a new species obtaiued on the west coast of India, which he proposed to 

 call Phymastrcca irregularis. 



Dr. J. S. Garson read a paper on the anatomy of the Pygmy Hog of 

 Nepaul (Porcula salvania of Hodgson), as exhibited in a female specimen 

 of this animal which had lately died in the Society's Gardens. Dr. Garson 

 came to the conclusion that this animal was not sufficiently different from 

 the true Pigs (Sus) to warrant its generic separation. 



A communication was read from Mr. Osbert Salvin, containing an 

 account of a series of birds collected by Capt. A. M. Markham, R.N., at 

 various points of the western shores of the Pacific, from Esquimault on the
