350 Miscellaneous. 



Figs. 13 H, 14 H, and 15 H. Three figures copied from the plate accom- 

 panying Professor Huxley's paper; described as " Cyatholiths 

 from the Atlantic Mud." The central corpuscle with its clear 

 space, a, in the centre is shown in figs. 13 and 14. The "granular 

 zone," g z, is shown in tig. 15. 



Fig. 16 represents a two-celled or chambered coccosphet-e — being appa- 

 rently the first stage in the formation of the coccolith-coxeved 

 Textularite and Hotali^ which have been described by me in 

 former papers, and of which mounted specimens are extant. 



Fig. 17. A coccolith of C. Carterii as seen in preserved specimens, an 

 aggregation of gi-anules being observable around the stem be- 

 tween the outer and inner disks, the so-caUed " granular zone " 

 of authors. 



Fig. 18. Sporangium of a protophyte from Bengal, probably allied to 

 Ankistrodesmus : a. the globidar colourless and transparent 

 sporangial cell ; bbb, the kidney-shaped fi'onds of same. These 

 never have &Jlagellum or cilia, and are not zoospores. 



N.B. In figs. 5, 7, and 11 D the letters indicate the same 

 portions of the structiu-e. 



MISCELLANEOUS. 



On Anguillula intestinalis, a neiv Nematoid Worm, found by Dr. 

 Normand in subjects attached hy Diarrhoea of Cochin China. By 

 M. Bavay. 



In the post mortem 'examination of a man who died of diarrhoea 

 of Cochin China, Dr. Normand found a very small worm, which he 

 sent to me as distinct from my Anguillula stereo rali s* , which, how- 

 ever, was associated with it in the intestine. Having subsequently 

 met with it in four other cases, I have ascertained that it is really 

 distinct ; and I think it useful to give a description of it. 



I have been unable in this Nematoid to distinguish the arrange- 

 ment of the muscular bands ; and although I have examined more 

 than two hundred individuals, I have never seen any spicula ; hence 

 it is impossible at present to fix its position in the modern classifi- 

 cations, such as that of Schneider. I shall therefore give it provi- 

 sionally the generic name of Anguillula (sensu latiori), and distin- 

 guish it by the specific name intestinalis.
