valueless except as a generic record. Asa genus, Conzwlus is 
generally distributed over the state. In considering the dif- 
ferent species, only such localities are recorded as have been 
personally verified by the examination of specimens. 
This species is quite common and of general distribution 
in both peninsulas. Streng reports ‘‘/fwdvus” as ‘‘rare” in 
Kent county. 
48a. CONULUS FULVUS MORTONI (Jeffreys). 
Two characteristic examples collected by Lothrop at East 
Saginaw are the only ones seen from this state. 
It is an interesting and curious coincidence that the 
locality where these specimens were found is also one of the 
few places in the state where the carinated form of Stvobzlops 
has been collected. 
49, CONULUS CHERSINUS POLYGYRATUS Pils. 
Although not as common as the typical fw/vus, this form 
has apparently an equally extensive range over the state. In 
fifteen localities represented by fu/vus, this form was found 
associated with it in seven. It was the only species found in 
material from Mackinac Island, while at Kast Saginaw it was 
associated with fulvus mortont. 
50. ZONITOIDES NITIDUS (Mull.) 
A common and abundant species of general distribution. 
51. ZONITOIDES ARBOREUS (Say). 
Abundant everywhere. 
52. ZONITOIDES MINUSCULUS (Bimnn.) 
Common and of general distribution. 
53. ZONITOIDES EXIGUUS (Stimp.) 
Northern part of the state. The only locality reported 
south of Wexford county is Grand Rapids. 
54. ZONITOIDES MILIUM (Mse.) 
Scattering returns indicate a general distribution for this 
species. | ‘“ Very raréin Kenticounty,”) Strens. 
55. GASTRODONTA INTERTEXTA (Binn.) 
The only Michigan examples known are in the Agricul- 
tural College museum and were collected many years ago in 
Sanilac county. Evidently rare as it has not been reported 
from any other locality.
