uncommon on the London clay.” I have now to report that it occurs 
plentifully in the nursery-gardens of Miss Allman, at Horsham, from 
whence, last autumn, I received many specimens of all ages.— WILLIAM

Linnean Society or Lonpon. 
March 4, 1880.—Prof. Attman, F.R.S., President, in the chair. 
The following gentlemen were elected Fellows of the Society :—S. M. 
Bairstow (Huddersfield), John T. Carrington (Aquarium, Westminster), 
Prof. P. M. Duncan (King’s College, Lond.), R. M. Middleton, jun. (West 
Hartlepool), S.O. Ridley (British Museum), and J. Charters White (Belgrave 
Road, S.W.). 
Mr. Middleton exhibited two skulls of Babirussa alfurus, Less., from 
Borneo, which, though quite adult, were both distinguished by the 
remarkable smallness of their tusks. 
Dr. A. Giinther brought forward two deep-sea fishes obtained during 
the ‘ Challenger’ Expedition, viz. Hchiodon and Scopelus, to illustrate two 
kinds of luminous metameric organs, first distinguished by Dr. Usson, 
which he described and designated as the “lenticular” and “ glandular” 
kinds. Whilst admitting the great morphological resemblance of the 
former to an eye, he (Dr. Giinther) gave reasons which induce him to 
dissent from the view that they are organs of vision. He showed that 
their structure is not opposed to the view that they, like the glandular 
kind, are producers of light, and that probably this production of luminosity 
or light is subject to the will of the fish. 
Mr. J. Jenner Weir, on behalf of Mr. Edward A. Nevill, showed the 
stuffed head of a Prongbuck (Antilocapra americana), shot by the latter in 
the Rocky Mountains, August, 1876. On the median nasal region of this 
specimen what appeared to be a short unbranched third horn was developed. 
In the discussion which followed it was suggested that the abnormality in 
question might be an elongated warty growth rather than a true horn, after 
the type of the rear horns. <A further careful examination into its structural 
conditions was recommended. 
Dr. Francis Day next recounted the peculiarities and descanted on the 
geographical distribution of the Hebridal Argentine (Argentina Hebridica). 
Only three examples have hitherto been recorded {all by Yarrell) as taken 
in Britain, viz., two in Rothesay Bay, Scotland, and the third off Redcar,
