connected by intermediate links, and can therefore be regarded only as varieties of one 

 specific form, as Messrs. Parker and Eupert Jones have already observed. Many of the 

 shells here delineated, which have not, to my knowledge, been hitherto drawn, present 

 many features of interest to the students of these Microzoa. These I have for the most 

 part arranged as subvarieties of forms already named ; and I have endeavoured, as far as 

 expedient, to add as few new names as possible to the already too perplexing medley of 

 synonyms. 



I do not expect the following pages to be exempt from those faults which are so apt 

 to creep in when studying such minute forms as those here described; but as all these 

 shells have been drawn and studied by me while in a recumbent position on an invalid's 

 couch, I trust that all defects will meet with a lenient criticism. Shut out in a gront 

 measure, as I unavoidably have been, from access to many of the works of reference, and 

 unable to retain the few I succeeded in obtaining, except for a very short time, I have

had to contend with many disadvantages ; and therefore, if through these pngos there are 

 errors of synonymy or the like, those who have learnt from experience* the dilliculiles 

 which a person cut off from the advantages of our libraries, and never allowed to a^^inne 

 even a sitting posture from one year's end to another, has to contend with, will, I am 

 sure, look, with an indulgent eye on all minor shortcomings. 



Those who are desirous of becoming more thoroughly, acquainted with th(*se andotlu'r 

 roraminifera cannot do better than to study Dr. Carjiontcr's 'Introduction to the study of 

 the Foraminifera' *, and the monograph by Messrs. Parker and E-upcrt Jones on those of 

 the N. Atlantic and Arctic Oceans f, and their several memoirs on the nomeuchiture of 

 the Poraminifera {, and, for those of our own coasts, the excellent monograph hy Prof. 

 Williamson. The Paris basin and several recent deposits have been well explored by 

 M. d'Orbigny ; while the fossil forms from several foraminiferous deposits in Germnny 

 have been copiously figured and described by Prof. A. Reuss, who has furnished us with 

 a series of pictures unsurpassed both as regards numbers and excellency of drawing, and 

 one of whose memoirs is entirely devoted to the LagencB §. 



To the valuable information thus accumulated I now append these forms from th*' 

 abyssal depths of the Java seas, with the hope that they may help to extend our 

 knowledge of these marvellous little beings, and awaken the curiosity of many to senreli 

 for themselves among this uninteresting-looking *'mud," which forthwith, touched as 

 it were with a magician's wand,
