PANDALUS GURNEYI Stimpson. 

 Plate II, fig. 6. 



Pa n da /u s gurneyi Stimpson, Ann. Lye. Nat. Hist. N. Y., x, 128, 1871. Mon- 

 terey, Calif. 



The species which I take to be I*, gurneyi is very near P. dance. 

 Our adult specimens are smaller than F. dana ; rostrum longer, being 

 from one and a half to one and two thirds longer than the carapace. 

 Median dorsal spines 8 or 9, rather distant, ventral spines 9 or 10. An- 

 tennular peduncle only two fifths as long as acicle ; the fiagella are sub- 

 equal and one and a half times as long as carapace, the thickened 

 portion of the outer one being a little over half the entire length ; the 

 basal scale is rounded, not angled. 



Antennal scale as long as carapace, flagellum exceeding length of 

 body. 



Maxillipeds reaching three fourths the length of antennal scale, first 

 pair of feet reaching nearly as far. Right leg of second pair extends to 

 tip of acicle, carpal segments 1 7 ; left leg one third longer than right, 

 carpal segments about 45. 



As the last three pairs of feet are about the same length as in P. dance, 

 it follows that in the female the third pair does not reach as far beyond 

 the rostrum as in that species, or fails to reach the end of the 

 rostrum. 



In the male the last three pairs of legs are shorter than in the female, 

 and the propodus of the third pair is slightly re- 

 curved and narrowed at the extremity, forming a 

 margin against which the dactylus closes ; this is, if 

 Fig 15 Pandaius ] | ^ mistake not, the condition which Stimpson de- 

 ffTTi .Y^'t^l ' I scribes as ' subcheliform.' 



3'3o- 1 1 Sixth segment of abdomen one and a half times 



as long as wide ; seventh less than one and a half 

 times as long as sixth, 5 spinules on each side. 

 Otherwise as in P. dancz. 



Dimensions. — Ovigerous female (station 2961), length 77.5 mm., 

 length of carapace and rostrum 38.5 mm., of rostrum 25 mm.
