324 The Irish Naturalist. 



T*\xrx^\xr3. lapillus, Iv. — Two specimens, complete, but much 

 smoothed and worn. Present range, north and south. 



Chrysodomus (Fusus) contrarius, L.— Two almost complete 

 specimens, and fragments of at least half a dozen others. This reversed 

 form occurs throughout the newer Pliocenes, but is extremely rare in 

 our present seas. 



Pleurotoma rufa, Mont. — One complete specimen. Present range, 

 north and south. 



In addition to the above, there are a number of species 

 which are not j^et positively identified, and are withheld for the 

 present. Among them, is a Pecten, three species of Cardiuvi, 

 a Cardita % a Macfra, two species of Nassa, and two of Fusiis. 

 There are besides fragments of at least half a dozen other 

 species, quite indeterminable ; so that the total molltiscan 

 fauna which we have collected at Kill-o'-the Grange numbers 

 abottt thirty-eight species, represented by some 400 specimens. 

 As to the physical characters of this large assemblage, the 

 remarks appended to the note on Cyprina islandica appl}' to 

 all ; the shells are very hard and fresh-looking, almost 

 invariably broken, mostly with sharp angles and edges, thotigh 

 in some the edges are thoroughl}^ rounded ; some of them 

 are striated, and a few are beautifull}' polished. 



Before considering the faunistic characters of this assemblage, 

 it may be well to enumerate the other animal forms discovered. 

 Of CirripedeSj Balanus .^«;;^^n was represented by four pieces. 

 It is a species of northern facies, occurring rather sparingly 

 and generally in deep water. Several Ostracoda were detected ; 

 but they have not yet been named. A polyzoon washed out 

 of the spire of a univalve also awaits determination. Thanks 

 to the kindness of Mr. Joseph Wright, F.G.S., we are able to 

 state that Foraminifera are abundant in the cla}-, and to give 

 the following list of species obtained in abotit ir, lb. of 

 material sent to him. 



lYIlIioIina seminulum (Linne). — Rare 



lYI. trlcarlnata (D'Orb.) — Very rare. 



IVI. sub rotunda (Mont.) — Frequent. 



IVI. tenuis (Cz.) — Ver}' rare. 



Textularia globulosa, Ehr.— Common. A common fossil of the 

 North of Ireland Chalk. 



Bulimlna pupoides, D'Orb.— Rare. 



B. fuslformis, Will. — Frequent. 



BoIIvtna punctata, D'Orb — Rare. 



B. pllcata, D'Orb.— Rare. 



B. lobata, Br.— Rare. 



B. dllatata, Rss. —Common.
