Introduction. — The following Eeport deals with the Microzoa obtained 

 from the deep-sea soundings collected round Funafuti in 1896 by 

 H.M.S. ' Penguin,' Captain A. M. Field, E.N., commanding. 



I have previously published four reports on the Foraminifera and Ostracoda 

 of the various dredgings made by the Funafuti Expeditions between 1896 

 and 1898 * ; and the present report is practically final as regards the recent 

 material. For the privilege of examining the present very interesting 

 series of soundings I am indebted to Prof. J. W. Judd, C.B., LL.D., F.R.S., 

 and the Coral Reef Committee of the Royal Society. The samples wore 

 sent on to Melbourne, and reached me in January 1904. 



Condition of Material. — The collection of soundings made by H.M.S. 

 ' Penguin ' consists of 23 samples of dry Globigerina ooze and shell or 

 " coral sands," and 37 samples of soundings in grease, taken by the sounding- 

 lead. The former, and a few of the latter, were contained in glass bottles 

 and tubes, M'hilst the remainder of the samples in tallow were in paper 

 envelopes. After spending some time in cleaning the tallow samples, which, 

 by the way, were of an especially refractory nature, and examining them 

 microscopically, it was seen that the result did not justify the trouble, since 

 the cleaned material often yielded only a few specimens of the commonest 

 and most ubiquitous types of Foraminifera, chiefly of pelagic forms. The 

 present work is therefore mainly based on the results from the dry soundings, 

 although some of the more interesting of the tallow samples are included. 



Two of the dried soundings in this collection, viz. Nos. 3 and 19, were 

 partially examined by me when working in the Geological Laboratory at the 

 Royal College of Science, London ; and the results of a search for the 

 Ostracoda were embodied in my paper published in 1902, entitled " Some 

 Ostracoda from Funafuti." Those samples were then only partially worked 

 over and none of the Foraminifera noted, so that they have now been 

 examined more exhaustively, and the entire results herein included.
