Ornithological Notes from Sussex. — In the first week of October two 

 adult Red-ihroated Divers, with red throats, were shot off the Fish-market, 

 Hastings. About October 18th an adult female Long-tailed Duck was 

 shot from a pond at Ashburnham, near Battle, about seven or eight miles 

 from the sea. On Oct. 22nd I had offered to me three young Sheldrakes, 

 shot out of a flock of five on the previous day at Pett Level, near Winchelsea. 

 On the same day a young male Shag, Phalacrocorax cristatus, was shot at 

 the bottom of Ecclesborne Glen. On Nov. 8th I had brought to me a Fork- 

 tailed Petrel, washed up dead opposite the Marina at St. Leonard's ; its 

 gizzard contained a small seed only. — G. W. Bradshaw (Hastings). 



MOLLUSC A. 



Colpodaspis pusilla on the Devonshire Coast. — At a meeting of 

 the Zoological Society, held on Nov. 20th, Mr. W. Garstang read a paper 

 on this rare Gastropod mollusc, a specimen of which had been found by 

 him near Plymouth. The anterior part of the foot was not really bifid, as 

 stated by Sars, but possessed a pair of the large prolongations of its antero- 

 lateral angles, analogous to the anterior pedal cornua of many iEolids. 

 In this case, however, they were probably to be regarded as homologous 

 with the pleuropodial expansions of the Tectibranchia. The bulloid 

 shell, the radula, and the posterior appendage of the mantle pointed to 

 the close affinity of Colpodaspis with the Cephalaspidea; but the great 

 extent of the mantle, the small head, and the grooved tentacles were 

 important and primitive characters which it shared with the Notaspidea. 

 Whether Colpodaspis was an immature stage of some Philine-hke genus or 

 not, it furnished an indubitable connecting link between these two great 

 subdivisions of the Tectibranchia.

Linnean Society of London. 



December 6th, 1894.— Mr. C. B. Clarke, F.R.S., President, in the 

 chair. 



Mr. Walter Tothill was elected a Fellow. 



Mr. E. M. Holmes exhibited and made remarks upon a small collection 

 of Japanese Marine Algae, some of which were of considerable rarity in 

 European collections. 



Prof. D. Campbell brought forward some illustrations of the relations of 

 Vascular Cryptogams as deduced from their development. His remarks, 

 which were listened to with great attention, gave rise to an interesting
