OEVERAL years ago a series of soundings from the Abrohlos Bank, taken during the 

 cruise of H.M. Surveying-ship 'Plumper' in the month of May 1857, were placed 

 in the hands of Prof. W. K. Parker for examination. The samples were small, as 

 was always the case before the introduction of modern sounding-appliances, but they 

 were found to contain Microzoa of fairly representative character; and arrangements 

 were made by Professors Parker and Rupert Jones for the publication of the results 

 obtained from their investigation. The necessary plates were drawn and lithographed 

 by Mr. George West, funds for the purpose having been supplied by a grant from the 

 Eoyal Society ; but circumstances prevented the work being further proceeded with at 

 that time, and it has since remained in abeyance. The preliminary examination of the 

 material supplied the basis of three columns of one of the Supplementary Tables 

 appended to Messrs. Parker and Jones's work on North-Atlantic and Arctic Forami- 

 nifera in the ' Philosophical Transactions ' for 1865 ; but, beyond that, little or nothing 

 has appeared in connection with the subject. The publication, in the interval, of 

 numerous memoirs treating of recent Foraminifera, and notably the ' Report ' by one 

 of us upon the Foraminifera obtained by the ' Challenger ' Expedition, has deprived the 

 plates of some of their novelty; but though, beyond a few previously undescribed 

 forms, they contain little that can now be regarded as new to science, the figures, 

 which for the most part are very accurately drawn, often illustrate structural modifica- 

 tions of considerable interest ; whilst collectively they form a series likely to be of 

 service to the working naturalist. From another point of view, namely the distribution 

 of species, they have also a definite value. 



We propose to limit the present communication to a catalogue of the species, accom- 

 panied in certain cases by brief notes relating to their distribution, and to any peculi- 

 arities of structure exhibited by the specimens, together with such special points of 

 interest as may have been observed in connection with them. More than this appears 

 needless. In point of fact, the recently published 'Challenger' Report, to which 

 allusion has been made, deals somewhat exhaustively with a very large proportion of 

 the species in the Abrohlos collection, and it would be a waste of labour and of space 

 to repeat descriptions and references already easily accessible. We have therefore 

 omitted all lists of synonyms, matters connected with nomenclature, and the like,
