Glandina truncata, Gauuxin. (p. 84.) 
Found also in North Carolina. 
Glandina Texasiana, Preirrer. (p. 87.) 
Found also in Louisiana. 
Macrocylis Voyana, Newcoms. (p. 93.) 
A smaller variety of 9 mm. greater diameter is found at Los Angeles. 
Macrocylis Hemphilli, W. G. Brxv. 
Plate II. Fig. M. 
At Olympia, Oregon, Mr. H. Hemphill collected several specimens of a 
Macrocyclis, which appears to be distinct from, though nearly allied to, MZ. Van- 
couverensis. It may be best described by saying that 
The umbilicus is narrower and not excavated so much, the termination of 
the last whorl not receding from the umbilicus as in all the forms of Vancou- 
verensis and concava ; in all, the whorls are more or less strongly striated with- 
in the umbilicus, often*almost ribbed in concava ; not so in this shell; the 
texture of the shell is glassy like Hyalina, and there is no trace of the micro- 
scopic spiral lines found in all the other forms ; beneath, the last whorl is pro- 
portionately wider. The greater diameter is 14 mm.; lesser, 10; height, 5. 
The jaw and lingual dentition are as usual in the genus. I could not dis- 
tinguish the characters of the central tooth in this species. 
Zonites capnodes, W.G. Binn. (p. 98). 
Plate III. Fig. C. 
Living specimens received from near Knoxville, Tenn., through the kindness 
of Mrs. George Andrews, have enabled me to figure the genitalia. The genital 
bladder (g. b.) is large, globular, on a short, narrow duct : the penis-sac (p. s.) 
has the same peculiar accessory process which I have detected in those of 
Z. levigatus, Rugeli, fuliginosus, friabilis, and inornatus. There is a vaginal 
prepuce. 
It is in many individuals more easy to distinguish capnodes from fuliginosus 
by the dentition than by the shell. 
Zonites fuliginosus, Grirr. (p. 100.) 
In a specimen from Indiana, sent me by Mr. F. Stein, I find the same acces- 
sory process to the penis-sac noticed above. It is not given in Leidy’s figure 
in Vol. I.
