Order PRUNOIDEA, Haeckel. 



Genus Cenelltpsis, Haeckel. 



The test is a simple elliptical latticed shell, without radial spines. 

 Forms of this gen ns are very numerous and generally distributed in 

 the Culm radiolarian rocks. 



Cenellipsis sp. a. PI. XXVI. fig. 1. Test regularly oval ; long 

 diameter -21 mm., transverse - 1G mm., thickness of wall "015 mm. 

 Both in form and size this agrees closely with specimens from 

 Mullion Island (Quart. Journ. Geol. Soc. vol. xlix. 1893, p. 217, 

 pi. iv. figs. 5, 6). From Carzantic Quarry, near Launceston. 



Cenellipsis sp. b. PI. XXVI. fig. 8. Test elongate oval ; long 

 diameter - 2 mm., transverse *14 mm., thickness of wall about 

 •02 mm. Codden Hill Quarry, near Barnstaple. 



Cenellipsis sp. c. PI. XXVI. fig. 2. Test short oval ; length 

 •17 mm., breadth - 145 mm., thickness of test *01 mm. From 

 Bamshorn Down and Carzantic Quarry, near Launceston. 



Cenellipsis sp. d. PL XXV. fig. 16. Test regularly elliptical ; 

 length -125 mm., breadth -1 mm., and "01 mm. in thickness. Barns- 

 horn Down. 



Genus Ellipsoxiphtts, Dunikowski. 



The test is a simple elliptical latticed shell, with a radial spine at 

 each pole. 



Ellipsoxiphus sp. a. PI. XXVI. fig. 10. Test oval, *22 mm. in 

 length and -2 mm. in breadth, with a stout, tapering, obtusely -pointed 

 spine at each pole. The spines probably were equal in length 

 originally ; the longest is now *17 mm. From Tregeare Down, 

 near Launceston. 



Genus Drupptxia, Haeckel. 



Test elliptical, of two concentric latticed shells without radial 

 spines. 



Druppula sp. a. PI. XXV. fig. 17. The test is regularly ellip- 

 tical; length *14 mm., breadth -115 mm., the inner test *04 mm. in 

 diameter. No connecting-rays are shown. Bamshorn Down. 



Druppula sp. b. PL XXVI. fig. 7. Test regularly eUiptical ; 

 length "18 mm., breadth -155 mm. The inner test is "07 ram. in 

 diameter ; it is connected by numerous rays with the outer. 

 Carzantic Quarry, near Launceston.
