indicates that pegs appear continuously on joints between those 

 thus separated, inclusive; e. g., 11-13 means that a peg appears 

 on each of the eleventh, twelfth and thirteenth articles. In 

 ascertaining the spinules of the legs the method was in general 

 to clear and mount the legs in order, with anterior faces down. 

 It was thought sufficient for the present purposes to count the 

 spinules of dorsal and ventral lines, in the case of femur and 

 tibia, and of those that appear on the intermediate caudal 

 surface in the three lines of hair approximately caudodorsal, 

 caudomesal and caudoventral in position, since the spinules of 

 the anterior surface vary in similar degree. Thus the abbrevia- 

 tions at the heads of the minor columns stand respectively for 

 dorsal, ventral, caudodorsal, caudomesal and caudoventral. • 



The lengths of the several individuals furnishing the data 

 given in the several tables are as follows: 



Bermuda a, 23 mm. Boston a, 23 mm. 



Bermuda b, 19 mm. Boston b, 20 mm. 



Bermuda c, 21 mm. Boston c, 19 mm. 



Bermuda d, 22 mm. Boston d, 22 mm. 



Bermuda e, 16 mm. Beaufort, N. C, 20 mm. 



France, 25 mm. Texas, 25 mm. 



Salem, Mass., 26 mm. Washington, D. C, 17 mm.
