are all more or less constricted in the middle. The extra space thus 

 gained is occupied by the terminal segment (gth) which in the middle is 

 about one-fifth the entire length of the, body. The dorsal surface is 

 marked on each side with three interrupted longitudinal brownish bands 

 which lose their individuality on the first and last segments of the body. 

 One band is a little to one side of the mid-dorsal line ; between this and 

 the corresponding band on the opposite side the body is usually some- 

 what discolored by the contents of the alimentary canal. A second band 

 is between the first and the margin of the. body, on a line with the spi- 

 racles. The third band is along the margin of the body. These bands 

 examined under high power objectives (!- in. obj., i in. E. P.) show ir- 

 regular ridges radiating from central points (Fig. 3). At intervals between 

 these ridges are little circular openings through the integument from some 

 of which little balloon-like appendages or sacs protrude probably sense 

 orgns of some sort which under low power objectives appear like glist- 

 ening points. 



The ventral surface of the body (Fig. 2) is gray without markings. The 

 head appears to arise from the posterior portion of the ventral part of the 

 prothorax and is capable of considerable protrusion. Seen from below it 

 is roundish, bearing numerous tactile (?) hairs. A minute simple eye, 

 dark red in color, is situated on each side underneath and slightly behind 

 the base of the antennae. Antennae composed of three subcylindrical seg- 

 ments, the basal segment short and thick ; the middle segment five times 

 as long as the basal one and a little narrower ; bearing three long slender 

 spines on its outer half and one shorter stouter one near its tip. The ter- 

 minal segment which is about one-third as long as the middle segment 

 and is more slender, bears a long slender spine just beyond its middle 

 and another at the tip. In addition to these spines already described 

 minute ones are also found on the last two segments. Mouth parts yel- 

 lowish in color. Mandibles toothed, (labial or maxillary) minute, bear- 

 ing tactile hairs. The legs are slender ; coxae, trochanters, femora and 

 tibiae being well developed and each bearing one or more slender spines, 

 the tarsus consisting of a single segment, apparently in two parts ; a 

 stout curved pointed portion and a slender shorter pointed piece arising 

 near its base the whole resembling a crustacean chela (Fig. 5). Between 

 the legs of the right and left sides of the body are four pairs of long 

 slender spines arising from minute papillae. The anal opening is situated 

 about one-sixth the length of the body from the caudal margin, is diffi- 

 cult to distinguish, and is surrounded by numerous slender spines of 

 various lengths arising from minute papillae. The segmentation of the 

 body from below is indistinct except in the middle and at the extreme 

 sides. Near the posterior margins of the third to eighth abdominal seg- 

 ments a short distance in from the edge, on each side, a long slender 

 spine arises from a minute papillae. These spines are directed outwardly, 

 and when the larva is viewed from above appear to arise from the
