the end of the proximal third and bearing a pronounced inner tooth at 

 the beginning of the distal third, to a delicate, gently and almost evenly- 

 curved type in which the inner tooth at the base of the distal third is 

 often wholly absent. It is not surprising that Dohrn considered 3, 

 single specimen of this latter type a distinct species and named it 

 calif ornica, but in several of the series from a single locality the ex- 

 tremes of both are to be found, and calif ornica can not be considered 

 a race of lincare nor should the name be retained as Caudell has done.^

 retain also the name exilis upon size, coupled with a slight and natural differ- 

 ence in abdominal width, is unwarranted. Study of an extensive series shows 

 that, wherever a number of specimens from the same locality are available 

 for examination, such size variation is found. 



- The Territory of Misiones, Argentina, adjoins the State of Santa Catha- 

 rina, Brazil, the type locality of the present species. The type, a small female, 

 is given as 5 lines (10.5 mm.) long including the forceps, which are t >^ lines 

 (2.7 mm.).
