cephalic veil of other true Volutes. A very fine specimen of 

 Valuta papulosa having lately passed under my examination, I was 

 struck with the fact that it also showed, from the peculiar enamel 

 coat on the whorls and outer edges of the outer lip, that its mantle 

 must also have been similarly expanded ; though this character had 

 hitherto escaped notice from the shells having been cleaned, — this 

 peculiar coat, the great beauty and character of the shell, having been 

 destroyed. This led me to examine carefully the other species of 

 the family, and it is now clear that several species of the Volutes 

 have the same character. They may be divided thus : — 



* Mantle lobes largely expanded and entirely covering the spire, 

 which is often entirely hidden by a shell-deposit. 



1. Volutella angulata. 



** Mantle lobes moderately expanded, covering the lower side of 

 the spire, and leaving a callous band on the suture of the other part. 



2. Volutella Scapha. 3. Volutella imperialis. 4. Volutella cym- 

 biota. 5. Volutella Sophia. 6. Volutella volvacea ; and perhaps 7. 

 Voluta tuberculatum Swainson. 



*** The mantle lobes moderately expanded, not covering the spire, 

 the suture of the spire simple. 



8. Volutella papillosa. 9. Volutella fulgetrum. 10. Volutella 

 ancilla. 11. Volutella fusif or mis. 



The genus Cymbiola, which differs from Voluta in having simple 

 conical teeth, as described in a former number of this Journal, is 

 peculiar for having a narrow callous band round the suture, showing 

 that the hinder part of the mantle is expanded, as may be observed 

 in Cymbiola undulata, C. reticulata, C. maculata, C. pallida, C. Tur- 

 neri, C. zebra, and C. lineata : the two latter have been referred to 

 the genus Marginella, but they are perfectly distinct from it.

Observations on Notamia bursaria. By G. H. Kingsley, M.D. 

 To the Editors of the Annals of Natural History. 



August 4, 1852. 



Gentlemen, — I found several tiny specimens of Notamia bur- 

 saria today, about low-water mark, off Harriet Lodge, West Cowes, 

 attached to pieces of seaweed and decaying wood. 



The water was as usual very foul and the specimens exceedingly 

 dirty, so much so, that they might easily have been overlooked 

 without the aid of the microscope. Under a good ^-inch glass, how- 

 ever, the beautiful pearly lustre of the general polypidom, the ex- 

 quisitely graceful shape of the individual cells, and the activity of 

 the polypes in the few" cells occupied by living tenants, soon gave 

 interest to the minute and exceedingly dirty zoophyte. 



The polypes resembled in general features the others of their
