4 THE NAUTILUS. 



The mantle retracted from the head, which thus exposed is one cm» 

 long — the jaw was easily seen, by the unaided eye, as a brown cres- 

 centic band in the superior lip, and with an ordinary magnifying 

 glass the ridges were easily seen. The whole animal is faded and 

 contracted, but still pliable. The next I obtain will be killed 

 in accordance with your directions in water, and will be kept for 

 you. 



Associated with the solea, and in damp places, I found some num- 

 bers of the slug which is given in d'Orbigny as Limax unguis Fer., 

 but they are not as large as represented in the plate. I found this 

 latter species very plentiful in the Prado at Montevideo and always 

 several individuals together. This latter is in contrast with Veroni- 

 cella, which were alone and widely separated. 



I had a few Chitons of both species mentioned in the first part of 

 this letter, alive in my aquarium bottle, for a few days in my room, 

 with a long strip of glass upon which I coaxed them to crawl for 

 the purpose of sketching for water-color work, and was surprised at 

 the rapidity with which they travel, and it was rendered all the 

 more decided when I compared it with the movements of the Ver- 

 onicella which I had in another bottle alongside. 



CONULUS FULVTJS MULL.i VAR. DENTATTTS. N. V. 



BY DR. V. STERKI. 



Among a number of Con. fiilvus from Jackson Co., Alabama,, 

 kindly sent by Mr. H. E. Sargent, last year, there were a few speci- 

 mens with distinct " teeth " in the base of the last whorl. Since 

 then, Mr. Sargent has paid attention to the matter, and a few day& 

 ago sent me some more specimens in two lots, one from the valley and 

 another from the hills. The latter were most small, young and half 

 grown, and most of them showed 1-2-3 small, white, testaceous 

 deposits in the base of the last whorl, at somewhat irregular inter- 

 vals, roundish or elongate in a radial direction. They are not high, 

 tooth-like, but quite distinct, whether seen through the shell, or if 

 near enough, from the aperture inside, and recall the same feature 



*The species was first described by Miiller, not by Draparnand. It may 

 be said again, that Conuhts is a genus founded on anatomic characters.
