PART 1 GARTH : PACIFIC OXYRHYNCH A 319 



all specimens of Herbstia, under whatever name originally recorded, 

 coming from southern California and northern Lower California, are 

 probably of this species. Similarly, all specimens of Herbstia from the 

 Gulf of California not belonging to the Panamic species H. tumida, 

 which occurs in the extreme southern end of the Gulf, are H. campta- 

 cantha. Specimens collected in recent years by the Velero III and Velero 

 IV support this geographical separation, and there should be no hesita- 

 tion in applying it to specimens collected in the time of Stimpson or 

 Lockington, even if these be no longer extant.
