N. M. no. 67989). Diagnosis.—Seven strong spines, one hepatic (paired) and one at widest part of carapace (paired); of the posterior spines the median reaches half again as far back as the lateral Figure ST.—Persephona ftnneganae, male, type (Brit. Mus.): Carapace, X3. Description.—Carapace, exclusive of spines, slightly longer than wide; subglobular, posterior half narrower than anterior. Surface covered with coarse, separated granules on a ground of fine, close granulation interspersed with punctae. Intestinal region partially defined by shallow furrows; two pairs of short, thumbnail, almost longitudinal indentations just behind the middle of carapace. Seven slender, acute spines; the hepatic are more triangular than the bran- chial spines and of subequal length; between them, but nearer the branchial spine there is a low, blunt tooth; of the posterior spines the pair on the posterior border are a little longer than the hepatic spines; the median or intestinal spine is about one and one-half times the length of the posterior lateral spines and forms a right angle with them. In a small specimen from Trinidad (66784) the median spine is longer and heavier than the other spines, being twice as long as the neighboring spines. " Dr. Finnegan overlooked
