Popp. ist. (Meine Bithynis longimana ist identisch mit Palaemon cae- 

 mentarius Popp, und muß bei Palaemon bleiben, aber der P. caemen- 

 tarnis ist nicht Cancer caementarius Molina.) Es hat mir Mühe ge- 

 kostet auszumitteln , was 1^ ö-p'pi g' s Leucosia paci/lca ist; ich glaube 

 aber jetzt, daß sie identisch mit Cyclograpsus «were« Dana ist , eine 

 Art, welche schwerlich beim Genus Cyclograpsus bleiben kann, 



3) Kleine geographische Irrthümer, die es doch aber gut 

 ist zu berichtigen. 

 In seiner Hist. nat. des Crustacés sagt Milne-Edwards, das 

 Genus Eurypoclius finde sich im Indischen Ocean , die einzige damals 

 bekannte Art lebe an den Falklandsinseln ! In D'Orbi gny's Voyage 

 lesen wir, das Vaterland des Panopeus crenatus sei»Callao (Chile)«, 

 und in demselben Werke ist eine bei Lima gefundene Potamia als 

 Pçtamia chilensis beschrieben, und natürlich von Nicolet unter 

 den chilenischen Crustaceen aufgeführt !

19th June, 1894. — Mr. Sclater exhibited the skin of a Monkey of 

 the genus Cercopithecus , and pointed out that it unquestionably belonged to 

 the local form which he had spoken of in his recent paper on the Cercopi- 

 theci as Cercopithecus diana ignihis. Mr. Sclater also exhibited the typical 

 specimen of Cercopithecus Grayi , Fraser, formerly in the Knowsley collec- 

 tion, and stated that it was the same as C. Erxlebeni, Pucheran. — Mr. H. 

 Scherren, F.Z.S., exhibited a bottle in which an amphipodous crustacean 

 [Amphitoe littorina) had built a nest and a series of runs of sand and pieces 

 of weed. — Prof. Ray Lankester, F.R.S. , read a paper on the external 

 characters which distinguish the two Dipnoid fishes Lepidosiren and Proto- 

 pterus^ and pointed out that there could be no doubt that these two forms 

 should be referred to distinct genera. — Ur. Fowler exhibited a specimen 

 of antlers of the Fallow Deer, belonging to Mr. J. A. R. Wallace, of Loch 

 Ryan, which showed the effect of the removal of one testis on the develop- 

 ment of antlers ; and made remarks on the effect of different degrees of ca- 

 stration upon antlers, as shown by specimens in the Museum of the College 

 of Surgeons. The continuity of variation displayed in the total length, and 

 lengths of brow- and tray-tines, in abnormal antlers in the Natural History 

 Museum was also commented upon. — Mr. P. Chalmers Mitchell, F.Z.S., 

 gave an account of his observations on the perforated flexor muscles in cer- 

 tain birds recently dissected in the laboratory in the Society's Gardens. — 

 A communication was read from Messrs. R. R. Mole and F. W. Urich 

 containing biological notes upon some of the Snakes of Trinidad , B.W. I. 

 To these notes was added a preliminary list of the species of Ophidians re- 

 corded from that island. — A communication was read from M. E. Simon 

 containing the second portion of a memoir on the Spiders of the Island of St. 

 Vincent, based on specimens obtained through the agency of the Committee 

 for the exploration of the Natural History of the West Indies. — A commu- 

 nication was read from Mr. W. E. Collinge containing the description of 

 a new species of Slug of the genus Janella from New Zealand , and giving
