ANNELID GENUS CAMBARINCOLA — HOFFMAN 341 



3. Prostate nearly as long as spermiducal gland; spermatheca long, slender, and 



not entally enlarged (western Virginia). 



Cambarincola holostonia, new species 



Prostate less than half as long as spermiducal gland; the latter unusually 



stout and strongly curved; spermatheca with a narrow ectal duct and large, 



subglobose ental bulb (Kentucky) . . Cambarincola nieyeri Goodnight 



4. Peristomium at least with four blunt lobes on its dorsal half; dorsal jaw 



generally at least somewhat longer and larger than the ventral .... 5 



Peristomium at the most divided into dorsal and ventral halves, the dorsal 



without lobes; jaws essentially subequal in size at least in lateral aspect . 6 



5. Head relatively larger (fig. 43), dorsal jaw distinctly broader than ventral 



(fig. 44) ; spermiducal gland comparatively small with respect to the pros- 

 tate (central eastern Kentucky and Indiana west through the Ozark 

 region into Kansas and Oklahoma, the diagnostic characters becoming 



accentuated westwardly) Cambarincola chirocepbala Ellis 



Head relatively smaller (fig. 39), dorsal jaw only slightly broader than 

 ventral (fig. 40) ; spermiducal gland relatively large in comparison with 

 the prostate (North Carolina and Tennessee north to New York, west in 

 the Great Lakes region to Wisconsin). Cambarincola philadelphica (Leidy) 



6. Prostate gland at least half as long as spermiducal gland, usually subequal 



in length; latter elongated, slender, not recurved (fig. 38); spermatheca 

 with a long ectal neck and a moderate ental bulb (western margin of the 

 Great Plains in Colorado and adjacent states). 



Cambarincola macrodonta Ellis 



Prostate less than half as long as the stout, recurved spermiducal gland; 



spermatheca with a very short ectal duct and a large, globose ental bulb 



(Kentucky) Cambarincola meyeri Goodnight
