before him not T. Vejdovskyi, but T. McGregori. The 

 specimens sent to Professor Beddard at his request were 

 not closely examined, hence the error. 



Telmatodrilus McGregori, sp. nov. 



Definition. — Body not stiff, less sluggish, and more tapering towards the 

 tail than in the former species. Spermathecae opening in front of and between 

 the ventral and lateral fascicles of setse in X. Setae distinctly uncinate, espec- 

 ially those of the ventral fascicles. 



Habitat. — California, in the Sierra Nevada Mountains, 

 generally at high altitudes, lower in the northern part of the 

 State than in the southern. Specimens are in the collection 

 from the following localities: Castle Crag, Shasta County, 

 in an irrigation ditch close to the hotel; Phil Hope Spring, 

 about six miles east of the town of Coulterville, Mariposa 

 County, and a few miles north of Dog Town, at the top of 

 the gulch: 3^ — Spring Meadow, on the east side of the 

 North Fork of King's River, Fresno County, at an altitude 

 of about 8,000 feet; in springs on the east side of Dinkey 

 Creek, Fresno County, a mile or so from Frank Dusey 

 Camp, near the head-waters of the creek, at an altitude of 

 6,000 feet. 



The species is named for Richard C. McGregor, to whom 

 the author is indebted for many new species of Oligochaeta. 



Detailed Description. 



As will be seen, the principal character concerns the 

 spermathecal pores, which in T. McGregori are situated in 

 front of the lateral intervals, while in T. Vejdovskyi they 

 are found in front of the ventral interval. 



Body. — Length in fully extended specimens 40 to 60 mm., 

 width about i mm. Body strongly tapering towards the 

 tail. More slender and more active than T. Vejdovskyi. 



SetcB. — Beginning with somite II, there are four fascicles 

 in every somite, each containing from 6 to 14 setse. The 

 setse of the lateral fascicles are indistinctly uncinate, while 

 those of the ventral fascicles are distinctly so. The anterior 

 setse, or those in somites II to IX inclusive, are larger than
