margins nearly parallel, obtusely pointed behind, in front bilobed 

 and deeply grooved, with the anterior lamina notched in the centre ; 

 the lateral angles much j)roduccd and recurved." 



I obtained this species on two occasions. The first s{)ecimen was 

 procured by me whilst dredging iu Weymouth Bay, on the 15th of 

 December 1855, and the second specimen in the same month of the 

 following year. Both these individuals, as soon as I had completed 

 my notes, I sent to Mr. Hancock, who received them in good con- 

 dition, and who, in conjunction with Mr. Alder, I am happy to say, 

 has made drawings of all the species described in this paper, — I trust, 

 in order to enrich, at an early period, another number of their ad- 

 mirable work on the Nudibranchiate Mollusca. ]Mr. Hancock sug- 

 gests for this species the specific name oi fmbinata ; but, whilst 

 admitting the propriety of the name, I trust he will fall in with, my 

 wish of identifying the district in which it was first taken. 



I would here draw attention to the irregular appearance of some of 

 the Nudibrauchs. Two species of Doris, formerly obtainable iu Wey- 

 mouth Bay in moderate abundance, are now scarce ; Eolis papillosa, 

 at one time very abundant, is now represented by an occasional speci- 

 men : these are all tidal species. Eolis coronata and Lnndshurgi were 

 never very plentiful, and are not less scarce than fonnerly ; but far 

 different is it with Polycera 4-lineata and Antiopa cristata. Some 

 three years since, we could obtain a dozen of each of these species any 

 day — I have seen three in one net (both these species appear to be 

 gregarious) ; whilst during the whole of the past summer my cap- 

 tures have not exceeded half a dozen of both species for the whole 

 year. The dearth was occasioned by the severe winter we had some 

 few years since, and which also destroyed many fish, and rendered 

 Ada?nsia palliata very rare. 



Description of Six hitherto Undescribed Species of 

 Bats. By Robert F. Tomes. 



1. ScOTOPHILUS MICRODON, n. s. 



The present species is one having the same subgeneric characters 

 as the common PipistreJle of Europe and the Scot. Greyii and S. 

 jmrnilns of Australia. To the latter species it is, by the form of its 

 head and ears, most nearly affine, but may at once be distinguished 

 from it by its greater size and by its smaller teeth. 



The crown is but little elevated above the facial line ; but the 

 muzzle, although short, is moi-e pointed than is usual in the flat- 

 crowned species. The ears are very small, nearly as broad as high, 

 with the outer margin slightly hollowed out about the middle, below 

 which is a faintly develojicd lobe, and immediately above which is 

 the tip of the ear, — the latter being obtusely angular, and directed 

 outwards. The inner margin is very much rounded, especially at 

 two-thirds of the distance from the base, where the convexity is so 

 prominent as to be quite as high as the tip itself, the portion be- 

 tween this prominence and the tip being nearly horizontal. Alto- 

 gether the ear bears some resemblance to that of Miniopteris. 

 Scot, pumilus is the only species which has ears of form similar to
