TEETH ON CLAWS OF ADULT SPIDERS. 



figured for the first leg, were found on each leg of the animal, 

 both on the right and on the left side. These claws were all of 

 the normal type but possessed relatively fewer teeth than those 

 on the claws of other specimens of the same species. 



Fig. 2 represents four claws on the second leg of the second 

 female of Theridimn tepidariomm, the claw bearing three teeth 

 being an additional inferior one. 



Figs. 3 and 4 show on the posterior claws double rows of 

 teeth, the additional row lying close to the normal and more 

 regular one. The claws in Fig. 3 are from the third leg of 

 specimen seven of Epeira benjamini and those in Fig. 4 from the 

 fourth leg of specimen four of E. mannorea, both in Table I. 



In conclusion I wish to thank Dr. T. H. Montgomery for the 

 many specimens which he placed at my disposal and for his kind 

 suggestions in my work.
