MARINE BIOLOGICAL STATION ON PUFFIN ISLAND. 41 



sea-water on the, spot, especially in cases where a muddy deposit is found. 

 The siftings so collected should be carefully preserved in bottles with spirit, 

 and labelled (inside) with a good B.B. pencil, while a part should be kept as 

 long as possible in sea-water and examined in the fresh state. The water 

 remaining in the tub in which the material has been washed, should Ijc 

 poured through a fine muslin bag or net, made for the purpose, and the 

 contents of this net should also be carefully preserved for future examination, 

 as in this way some of the rarer forms are often taken. 



Notwithstanding the small amount of material examined by me, I have 

 been able to add eight new species to the locality, one of which is new to 

 British seas ; these are as follows : — MilioHna puhhella, d'Orb. ; HapJojohra- 

 gmium agghitinana, d'Orb. ; Ammodiscus spectabilis, Brady ; Textularia 

 trnchus, d'Orb. ; Lagena ghh<>sa, Mont. ; L. clavafa, d'Orb. ; L. laevigata, 

 Reuss ; and Gloldgerina huUnides, var. trihba, Reuss. Two of these are 

 worthy of further note, viz. , 

 MiHolina pulcheUa, d'Orb. (sp). 



Mr. H. B. Brady, in his Challenger Report, pi. iii, figs. 10 — 13, and M. 

 Terquem in his memoir on the Foraminifera of the Upper Pliocene beds of 

 the island of Rhodes, figure this form. Mr. Brady says, M diolina puhhella 

 is not uncommon amongst the larger Miliolpe of comparatively shallow water 

 at depths of less than 100 fathoms. It occurs on the northern portion of our 

 own coast, and occasionally elsewhere in the Xorth Atlantic, in the 

 Mediterranean, and more rarely amongst the East Indian Islands. It is 

 therefore of considerable interest to have met with it in Liverpool Bay. 

 Ammodiscus spectahihs, Brady. 



One perfect and one broken specimen of this species were obtained amongst 

 the material dredged off Penrhos, Avhich answer in detail to those described 

 and figured by Mr. Brady (Report on the Challenger Foraminifera, vol ix., 

 pi. xxxviii., figs. 20 — 22) with the exception merely that those taken off 

 Penrhos are much smaller. This form is only known to have been taken from 

 two other localities, viz.. North Atlantic, and off" the East Coast of Buenos 

 Ayres in 1900 fathoms. It is therefore now added for the first time to the 

 British Fauna. 



It is interesting to find that many of the Foraminifera which we know as 

 inhabitants of the great ocean basins, also occur in the shallow seas round 

 our own' coast ; and this is of great importance in discussing the Geo- 

 gi-aphical and Bathymetrical distribution of these forms. 



I now give a list of the species found in 1890, with the localities. No. 5 being 

 the only one from which what could be called a good sample of a rich deposit 

 was obtained.
