near the shore throughout this whole region, but judged 

 that the disturbance caused by the storm had so mixed 

 things that the normal condition could not be well as- 

 certained. 



A superficial examination of the material procured by 

 these soundings shows the general resemblance that I had 

 anticipated ; a special feature is the great preponderance 

 of C'osoi7iodisctts from large to minute varieties ; Actin- 

 optychiis is abundant, and Pyxilla haltica and Py.K. dnhia 

 especially plentifu4 ; Rhizosolenia stylifornns and Biddul- 

 phia aurita are also abundant with Pleurosigma affine, 

 Melosira sculpta and Rhahdonema adriaticnm . Namcnla 

 lyra appears in many varieties and Triceratiuin favufi, 

 KupodiscH!^ argufi, Raphoneis amphiceros and R. yemm'}- 

 fera, Sfirrrella fastnosa, Pleurosigma balticmii, P. de- 

 roru))i, P. wansbeeckii and P. minutum are common. 

 Very large specimens of Namcula laiismma occur but 

 are rare. Near the shores of the bay Aulisciis and Ac- 

 t i nocyclus appear in variety some of which I cannot de- 

 termine, and a large Namcula with striation sometliing 

 like N. latissima but rather more distinct, and with a 

 broad elliptical outline without the produced extremities. 

 I have found this form in the fossil deposit here, and in 

 recent mud from the Thames river near Norwich (Jonn. 

 I do not think it has ever before been noticed. 



Foraminifera of many genera abound, not only in 

 soundings but also in the deposits in the creeks, ditches 

 and marshes ; at the upper end of Leete's creek at the 

 limit of tidal tlow I found but few diatoms, and those 

 mostly small fresh water varieties; but foraminifera were 

 abundant, of many species new to me; their shells did 

 not appear to be calcareous but showed a mosaic struc- 

 ture with markings of a somewhat regular irregularity 

 very similar to the shells of certain rhizopods, Nehela 

 collaris and Difflugia spiralis. 



Polycystina are common in soundings and dej~)Osits. I
