 collections. 



Toula, Franz. Die jungtertiare Fauna von Gatun am Panama- 

 kanal. II. Teil. Jahrbuch der k. k. Geolog. Reichsanstalt. 

 Wien, vol. 61, 1911, pp. 487-530 (1-44), pis. 30, 31 (1, 2). 



The hermit-crab (Petrochirus) noted and figured by Toula (p. 511, pi. 30, fig. 

 13) I have ventured to describe as a new species, combining as it does the char- 

 acters of the two nearly related Recent species which inhabit opposite sides of 

 the continent. The " Krabbenscheren " of Toula (p. 512, pi. 30, fig. 14) are de- 

 scribed below as a species of Callianassa, C. toulai.

The author is indebted to Dr. H. A. Pilsbry for the loan of the specimens of 

 Callianassa in the collection of the Philadelphia Academy of Natural Sciences 

 which were described by Brown and Pilsbry. They have been critically com- 

 pared with those collected by the United States Geological Survey.
