Glandina truncata, (iMi;r.ix. (p. 84.) 



Found ul^o in North Carnlina. 



Glandina Texasiana, Pfeiffek. (p. 87.) 

 Fdunil also iu Louisiana.

Macrocylis Hemphilli, w. n. Einn. 



Plate II. Yifi. M. 



At Olympia, Oregon, Mr. II. Hemphill collected several specimens of a 

 Macrocijdis, which appears to be distinct from, tliough nearly allied to, M. J^an- 

 cniivey-cnsis. It may l>e Ijest described l)y saying that 



Tlie umliilicus is narrower and not exca\'ated so nnu'h, the termination of 

 the last wliorl not receding I'rom the umbilicus as in all the foirus of ]'niivttii- 

 vercnsis and concara ; in all, the whorls are more or less strongly striated with- 

 in the uml)ilicu.% often almost ribbed in cnncava ; not so in this shell ;thi- 

 texture of the shell is i^lassy like Ifyaliim, and there is no trace of the micro- 

 scopic spii'al lines found iu all the other forms ; beneath, the last whorl is [iro- 

 portionately wider. The greater diameter is 14 mm. ; lesser, ](>; height,."). 



The jaw and lingual dentition aie as usual in the genus. I could not dis- 

 tinguish the characters of the central tooth in this species. 



Zonites capnodes, W. G. Bi\x. (p. ns). 



ri.ate III. Fig. C. 



Living specimens recciveil IVom near Kiio.-vcville, Tenn., through the kimlness 

 of Mrs. George Andrews, have enahled me to figure the gi'uitalia. The genital 

 bl.idder {(j. h.) is large, globular, on a slun't, narrow duct : the ]ienis-sac (p. .s-. ) 

 lias the same ]ieculiar accessory process which I liave detected in those of 

 Z. Iirrtijiifus^ 1,'uiicU. fi(liiji)ii)sii.<, J'riiihili.'^, and inornafn.^. There is a vaginal 



pi'epuce. 



It is in many individuals more easy to distinguish ca2)nodes from fidiijinnsii.i 

 by the dentition than by the shell. 



Zonites fuliginosus, Griff, (p. 100.) 



In a specimen from Indiana, sent me by Mi'. F. Stein, I find the sami; ai'ces- 

 sory process to the penis-sac noticed above. It is not given in Leidy's figure 

 in Vol. I.
