small fragment fr-om these beds that I sent to him by post ; the more 

 readily as Mr. Vine's high reputation as a palceontologist vouches for the 

 precise identification of such very variable and difficult objects. 



Mr. Vine adopts Dr. Carpenter's classification, viz. : — 



Imperforate. Perforate. 



MiliolidcE. Litnolidce. Lagenida. Glohigermidce. Nummulinidce. 



Grouping them as five families under two groups. 



Although the amount of material was not larger than a walnut, the 

 species and varieties were numerous, four out of the five families being 

 represented. Amongst them occurred a solitary specimen of Entomostraca, 

 probably a form of Carbonia. 



LIST OF SPECIES AND VAEIETES. 

 Sub-order, IMPEEFOEATA. Fam. Miliolida. 

 Fig. 1, 2. Miliola seminidum, var. (Biloculina) ringins, Linne. 



In England the Foraminifera are being arranged all under different 

 types. Thus of the Miliola, 2 seminulum is the type. The variety follows, 

 preceeded by its sub-generic title as above.) 



This variety is very widely distributed ; it is found common and large in 

 the Arctic Ocean (off Norway), at at from 30 to 160 fathoms. In North 

 Atlantic, rare on marginal X3lateau. British : off the Shetlands, rare in 

 120 fathoms. Very rare in Eiver Dee. Common in Tasmanian and Aus- 

 tralian seas. Fossil in Boulder clays of Cheshire (drift). Miocene, Yarra 

 Yarra, Victoria. The specimens from the material, are the largest and 

 finest that I ever saw. 



Figs. 3, 4. ilf. semmiditm, var. B. ringens, sub. var. elongata, D'Orb. 



Much smaller here than the B. ringens, it is more elongate and less glo- 

 bose in form ; it is simply a sub-variety of variety ringens, and cannot be 

 really called a species. Eare and small in North Atlantic, in 1450, 1950, 

 2050 fathoms. British : Eiver Dee, frequent. Fossil : Boulder clays, 

 Cheshire ; Yarra Yarra, Victoria. 



Figs. 5, 6, 7. M. seyninidam, var. ( Qidnquelocidina ) triangularis. D. Orb. 



This is a triangular form of the type which takes its place in some lo- 

 calities. Here the type is not found, but is represented as above. Very 

 rare and small in North Atlantic at various depths. Fossil in Miocene as 

 before, Eecent also in Mediterranean, Tasmanian seas, Indian Occean, 

 etc. Is very rarely recorded as a distinct variety, generally classed under 

 the typical name, Seminidimi. Here it is rather common in various sizes. 

 Fig. 8. ill. seminulum, var. (spiroloculina) planulata. Lamarck. 



This differs in some respects from the forms called " planulata " by 

 authorities, but I know of no other name for it. It is large, flat, much
