Fig. 371.—I'LEUROPRION MUEDocHi (After Benedict), x 85. either side of the median spine, all three lyino- lu^tween the eyes. The median spine is a little anterior to tlu^ other two. On the postei-ior portion of the head are eight spines in a transverse row, four on either side of the median line. Four of these spines lie hetwecni the eyi^s, one behind each eye, and one lateral to eaeh eye. Thei'e is also a s[)ine on (Mich of the antero-lateral projections. The iii'st pair of anteniue have the basal article large and dilated; the second article is almost as long as the tirst, but much more slender; the third is half as long as thr second; the fourth is twice as long as the third. The first pair of antennae extend to the end of the second article of the peduncle of the second pair of antenna-. The basal article of th(> second antennae is short, and does not extend beyond the basal article of the tirst pair of antenme; the second article is armed with three spines, and ex- tends to the end of the tirst pair of antennie; the third article is one and a half times longer than the second, and is armed with two spines; the fourth is two and a half times longer than the third, and is unarmed; the fifth is twice as long as the third, and is unarmed. The tlagellum is composed of three articles, the tirst of which is twice as long as the second; the terminal one is one-third as long as the second. The maxillipeds have a palp of live articles. The first segment of the thorax has eight spines in a transverse row, four on either side of the median line. The second segment has six spines in a transverse row, three on either side of the median line. The third segment has eight spines in a trans- verse row, four on either side of the median line, and an additional spine on either side anterior to the most lateral one. The fourth segment has two transverse rows of spines, with a constriction betwe
