264 BIOLOGICAL SURVEY OF 



Cragonidae 

 Crago Lamarck {C rang on) 



C. sEPTEMSPiNosus Say. (Rathbun, 1929, p. 20, fig. 24.) 

 Found usually on hard bottoms, from low water to 135 feet. 

 Our best stations were D 43 and S 6. It is best taken with a 

 fine-meshed seine in coves at low tide. The species breeds 

 during the summer. Stations: 53 dredging stations and 

 S 5, 6, 9. 



ScLEROCRANGON G. 0. Sars 



S. BOREAS (Phipps). (Rathbun, 1929, p. 20, fig. 25.) Taken 

 on rock bottoms, in 22 to 76 feet of water, not common. Sta- 

 tions : D 39-41, 94, 117, 135-137, 148. 



Suborder REPTANTIA 



Tribe ANOMURA 



Paguridae 



Pagurus J. C. Fabricius 



The two species which we have taken may be distinguished 

 by the following couplet : 



1 The antennal scale projects beyond the eye. The 



hands of the chelipeds are scarcely hairy . . . acadianus 

 The antennal scale falls short of the end of the 

 eye. The hands of the chelipeds are very 

 hairy pubescens 



P. acadianus Benedict. (Benedict, 1901, p. 454, text fig.) 

 Found on hard bottoms, from near low water to 95 feet. This 

 is the more common of our two species, and breeds during 

 the summer. Stations : D 3, 32, 75, 94, 120, 123, 124, 126, 

 129, 134, 135, 137 ; S 5, 8, 9, 11, 12. 



P. PUBESCENS Kroyer. (Rathbun, 1929, p. 28, fig. 37.) 

 Found in similar situations to the preceding, but more rarely, 

 from low water to 76 feet. Stations : D 36, 94, 126 ; S 43.
