only stipulating, as was necessary in tlie interests of the institution 

 under his care, that any types required by the Museum should be sent. 

 Mr. Joseph Wright, f.g.s., also, ^ith the genial readiness which ever 

 characterizes the true naturalist, has permitted me to search through 

 the floatings from the finer portions of the dredgings, from which 

 floatings he had obtained the Foraminifera already reported upon. To 

 these gentlemen I must express my gratitude. My tribute of thanks 

 is also due to Professor Haddon, Messrs. R. Welch, R, LI. Praeger, 

 B.A., and A. E.. Nichols, b.a., for their hearty co-operation; and to 

 Mr. E. A. Smith, f.z.s., and the Marquis of Monterosato, for their 

 kindness in determining certain critical forms. 



The material, as it came to me, consisted of floatings, shelly delris, 

 muddy sand, and fine gravel, from all of which the coarser part had 

 already been separated. There were also a few boxes containing such 

 of the larger shells as had been discarded. In the great majority of 

 cases the larger forms, those measuring more than a quarter of an inch 

 in length, are represented only by immature or fragmentary examples. 

 Eespecting these I can, therefore, give little or no information beyond 

 the mere fact of their occurrence. Far different is the case of the 

 more minute species. These are in many instances represented by a 

 very great number of specimens, sometimes showing marked varietal 

 modifications. Amongst them, too, there are several possessing special 

 interest, being either rare or hitherto unknown. 



I may here mention that, during the process of examination, cer- 

 tain species occurred in so large a number of the dredgings (not 

 always in great numbers, be it understood) as to impart a character- 

 istic " facies " to the moUuscan fauna. I refer, of course, to such 

 forms as are usually accounted more or less rare. Of these character- 

 istic species the following may be mentioned : — Ftdsellum lofotenscy 

 Sars ; Liostomia clamda, Lov. ; Mangelia Ir achy stoma, Phil. ; Neolepton 

 Clarhia, CI. ; Alvania alyssicola, Porb. ; Cardium minimum, Phil. 

 Scarcely less remarkable is the comparative rarity of Cyclostrema, 

 Jeffrey sia, Velutina, Turlonilla. Rissoa {Cingida) oltusa, Cantr., 

 usually one of the commonest of molluscs in British seas, only occurs 

 in one or two gatherings with even a moderate degree of frequency. 

 The group Bela is quite unrepresented. 



In some cases an attempt has been made to indicate the bathy- 

 metrical range of a species. The figures given refer only to the coasts 

 of Kerry and Cork. It seems far better thus to indicate the range of 

 the various species within the limits of the district under considera- 

 tion, rather than to give the vertical range of a widely distributed
