The species which I take to be P. gurneyi is very near P. dana. Our adult specimens are smaller than P. dance; rostrum longer, being from one and a half to one and two thirds longer than the carapace. Median dorsal spines 8 org, rather distant, ventral spines 9 or 10. An- tennular peduncle only two fifths as long as acicle; the flagella 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 17; 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 shghtly re- curved and narrowed at the extremity, forming a margin against which the dactylus closes; this is, if Fig. 15.
