Agatlna fnscata, Rafinesque, is probably not found in the United States. (See

Odotropis^ Raf. Xolotrema triodopsis, Raf. 

 Omphalina^ Raf. 



Oxijurus quadrilus, Raf., is a typographical error of my own in my "Notes,* 

 No. 4. No such name was proposed by him. 



Fossil HELiciDiE. 



Anomphahis Meekii, Bradley. Coal of Illinois. See Am. Journ. of Science, 



August, 1872. 

 Coelocentnim irregulare, Gabb. (see L. & Fr.-W. Sh., I. 23), and Berendtia Tay- 



lori, Pfr. (see same, 189). Lower California species are said to have been 



found fossil at Carson Valley, Nevada, latitude 39°, by Dr. J. G. Cooper, Am. 



Journ. Conch., IV. 217. 



VIII. SUPPLEMENT. 



Zonites "Whitneyi. (See p. 113.) There are 24—1—24 teeth on the 

 lingual membrane, all of the usual type ; four of them are laterals. 



Mesodon devia. (See p. 337.) The typical form has the same type of 

 dentition as the Salmon River variety. It is figured on PI. XVI. Fig. S. There 

 are 28 — 1 — 28 teeth. The thirteenth lateral has its inner cutting cusp split. 

 The jaw has fourteen ribs. The genital system has a small, globular genital 

 bladder on a long stout duct, ■which tapers greatly towards the bladder. Th« 

 penis sac is stout, long, cylindrical, with both vas deferens and retractor muscle 

 entering its apex; the ovary is long and narrow. There are no accessory 

 organs. 



I am indebted to Mr. Henry Hemphill for the opportunity of examining thf 

 above species.
