A PEESSED and mounted specimen of a small alga, labeled ' ' Laurencia 

 pmiiculata, Loo Choo Islands," was recently sent to me Uy Dr. E. 

 Perceval "Wright, with the suggestion that some Poraminifera which 

 had been entangled in its meshes might be worth examination, and 

 that at any rate it would be interesting to know what particular 

 species had lived amongst its miniatuj.'e branches. As the seaweed 

 itself was of some value, two or three square inches were taken, and 

 the portion as separated yielded examples of the following species of 

 Foraminifera, some of them in sufficient number to supply two or 

 three good mountings. 



Hauerina compre&sa, d'OrbigTiy. 

 Qiiinqueloculina suhrohmda, Montagu. 



,, hicornis, Walker and Jacob. 



,, ornatissima, Kauer. 



Pe7ieroplis ])ertu,ms, Batsch. 

 Vertehralina sir iota, d'Orbigny. 

 Orhitolites comjjlanatus, Lamarck. 

 Biscorlina rosacea, d'Orbigny. 



,, glolularis, d'Orbigny. 

 Planorlulina Mediterranensis, d'Orbigny. 

 Calcarina Spengleri, Gmelin. 



,, calcar, d'Orbigny. 



,, hispida, spec, no v. 

 Tinoportis haculatus, Montfort. 

 Cijmbalofora Poeiji, d'Orbigny. 

 Seterostegina depressa, d'Orbigny. 



Although a considerable list, considering that the entire weight 

 of seaweed, shells, and all could not be more than fifteen or 

 twenty grains, one or two forms were represented by a single speci- 

 men only, but no species has been retained of which a good charac- 

 teristic example, large or small, was not present ; doubtful f onns were 

 rejected, else the list might have been considerably extended. The 

 most abundant species of Calcarina was the pretty hispid modification 

 figured by Dr. Carpenter (Introd. Foram. PI. xiv., fig. 6), but not 

 hitherto described or named as far as I know. I propose to call this 

 C. hispida, and its characters will stand as follow. I have met with 

 larger specimens in Australasian sands, but have never seen any so 

 beautifully perfect. 



Calcaeixa Hispida, spec. nov. — Test free, unequally biconvex, ro- 

 talian : margin, thin lobulate orrowelled ; segments numerous, slightly
