a similar form from the lower Tertiaries of Hungary. This, how- 

 ever, appears to differ from the specimens above described in its 

 comparatively regular and complete septation. 



7. Texttjlaeia quadeilateea, Schwager. 



A clear-shelled compressed variety of Textularia, with four sharp 

 or carinate edges, first described by Schwager from specimens 

 occurring in a deposit of very similar nature to that under notice in 

 the Nicobar Islands. It is abundant in some of the Post-tertiary 

 materia] collected by Dr. Guppy in the Solomon Islands. As a 

 recent species it is not uncommon in the South Pacific, at depths 

 of over 400 fathoms ; in shallow water I have only record of its 

 appearance at one point, Humboldt Bay, Papua, 37 fathoms. 



10. Spieoplecta annectens, Parker & Jones, sp. 



Only one or two broken specimens of this rare and peculiar form 

 were met with. The ' Challenger ' dredgings furnished recent 

 examples from two localities, both in the region south of Papua, 

 depth 129 fathoms and 155 fathoms respectively. 



18-21. Pleueostomella, spp. 



The genus Pleurostomella is represented by four species, possibly 

 all the well-characterized forms at present known ; and it is note- 

 worthy that two of these were first obtained by Dr. Schwager from 

 the Nicobar deposit before referred to. Of three of the species, PL 

 alternans, PI. brevis, and PI. rapa^ the known recent distribution is 

 very limited. All of them were observed in the ' Challenger ' material 

 from the Ki Islands, 129 fathoms ; PI. alternans also in a dredging 

 at 2075 fathoms, in the Low Archipelago ; and PI. brevis (by Mr. 

 Pearcey) at 1950 fathoms, in the Southern Ocean. Pleurostomella 

 siibnodosa was met with sparingly at four * Challenger' stations in the 

 South Pacific and South Atlantic, ranging from 1375 to 2350 fathoms. 



2Q. Eheenbeegista bicoefis, sp. nov. (PI. I. fig. 3.) 



Test subspherical, regularly biserial, earlier portion, helicoid ; 

 margin entire; armed with two stout spines, one at each side, 

 directed outwards. Longer diameter about ^L inch (0*8 millim.). 



This is a curious modification of the Cassiduline type, somewhat 

 allied to Ehrenbergina hystrix, the short scattered spines of which 

 are replaced by two long processes, one at each lateral margin, pro- 

 truding at right angles to the longer diameter of the shell. The 

 segmentation is exceedingly regular, and the septal lines are scarcely, 

 if at all, depressed. 



Ehrenbergina bicornis occurs in two out of three samples of Suva 

 material ; and I have also recently found it in the chalky deposit 

 from New Ireland, described by Prof. Liversidge *.
