NO. 2174. EARTHWORMS OF THE FAMILY LUMBRICIDAE— SMITH. 167 



way from h to c. Oviducal pores on 14, slightly dorsad of h. Sperm- 

 athecal pores on 9/10 and 10/11, in line with dorsal bundles. Septa 

 6/7-9/10, strongly thickened and 5/6 and 11/12-14/15, a little less so. 

 Longitudinal partitions of the calciferous gland, usually 55-65 in 

 number. Sperm sacs in 9-12. Spermathecae included within the 

 septa 9/10 and 10/1 1 and not extending freely into the somite cavities. 



This is a species of the soil but seems to thrive equally well in the 

 undisturbed soil of woodlands and in that of cultivated fields and 

 gardens. It also abounds in the bottom lands of our rivers. 



H. caliginosus trapezoides is apparently the most abundantly 

 represented and certainly the most generally distributed of the North 

 American species of earthworms. There is scarcely one of the 

 United States in which collections have been made in which this 

 species is not found abundantly represented.
