All the segments of the abdomen are distinct. The sixth or terminal segment is rounded posteriorly. The inner ])ranch of the uropoda is broad with the extremity obliquely truncate; it extends a little beyond the tip of the terminal abdominal segment. The outer branch is one-fourth longer than the inner branch, is slightly narrower, and is produced to a narrow rounded extremity. All the legs are prehensile, with long, curved dactyli. There are two light longitudinal stripes or bands extending the entire length of the body, one on either side of the median Fig. 227.âNerocila munda (After Har GER). â 4. a.
