roptera, but from all other mammals. Pharyngeal air-sacs were also de- 

 scribed in the males of Epomophori mcnntrosus, Franqttett, and complus. — 

 Mr. J. Gwyn Jeffreys, F.R.S., read the third of the series of his memoirs 

 on the Mollusca procured during the »Lightning« and »Porcupine^ expeditions 

 1868 — 70. The present paper contained an account of the families from 

 Kelliklae to Tellinidae. Eleven new or hitherto unfigured species were de- 

 scribed. The geographical, hydrographical , and geological distribution of 

 the species enumerated were fully given. — Mr. F. C. Selous read a paper 

 on the South African Rhinoceroses, based upon specimens collected and ob- 

 servations made during nine year's hunting in Southern and South-central 

 Africa. Mr. Selous had come to the conclusion that in these countries only 

 two well-marked species of Rhinoceros existed — namely the square-mouthed 

 Rhhioccros siniu^, and the ])rehensile-lipped R. bicornis. — P. L. S dater.

May 5th, 1881. — Mr. C. Stewart exhibited and described an ovum 

 of Helix haeiiiastoma , remarkable for its great size as compared with that of 

 the animal. The generative organs are also peculiar. — Mr. George Busk 

 gave an abstract of a »Descriptive Catalogue of Cellepora collected on the 

 , Challenger' Expedition«, in which some thirty-one species of this Polyzoan 

 genus are referred to. Of these the North- Atlantic yields three from depths 

 ranging from 51 to 450 fathoms. The South Atlantic furnishes five species 

 from 500 to 600 fathoms. Of seven species from the immediate neighbour- 

 hood of Kerguelen Land (or so-called South Indian Region) three were got 

 from depths ranging from 20 to 150 fathoms. From the Australian Region 

 eleven species, with one exception [C. solida] , obtained from two to four 

 fathoms. Only two species obtain from the North Pacific Region, respecti- 

 vely 18 to 310 fathoms. From the South Pacific 304 species have been de- 

 rived, 45 to 150 fathoms being the extremes of depths, save in the case of 

 C. magellensis from 1325 fathoms. Mr. Busk arranges the .Challenger' 

 Celleporae into five sections distinguished by the general habit of the Zoariura, 

 viz.: 1. Encrusting or foliaceous expanded; 2. Hollow or more or less cylin- 

 drical; 3. Branched, solid; 4. Of massive irregular growth; 5. Fusiform. 

 He describes among others some thirty new species, and observes that as a 

 whole the genus Cellepora of this Expedition appear to belong to comparati- 

 vely shallow water. 



Anniversary Meeting, May, 24. — Prof. All man delivered his 

 anniversary address, his subject being »Recent Advances in our knowledge 

 of the Development of the Ctenophora«.
