. Bulletin - United States National Museum. Science. ISOPODS OF NORTH AMERICA. 177 The last four tlioniric segments lire each a littU> longer than any of the tirst three. The epimera are narrow, with i-ounded post-lateral angles. The live abdominal segments are of equal length. The terminal seg- ment is subtriangular with truncate extremit}'; its posterior margin is crenulate and fringed with hairs. The uropoda exceed slightly the length of the al)domen. The inner branch is about twice as wide as the outer branch; is obliquely truncate, and crenulate. The outer branch is narrow, rounded posteriorly, and smooth. Both branches are fringed with hairs. The legs are long and slender. Fiye spines are present on the merus of the pre- hensile legs. The gressorial legs are but slightly spinulose. Two specimens ex- amined were collected at Monterey Ba}^, Cali- fornia, by Mr. Heath. The description of this species of ^Ega by Dana as ^Egacylla Jecontll was from a 3'oung specimen. The indiyidual sent us is thought to be the adult form, and differs from Dana's description of the 3"oung indiyidual in the crenulated posterior margin of the terminal segment, in the truncated inner branch of the uropoda, and in the addition of two joints to the length of the flagellum of the second paii- of antenna?. ^GA TENUIPES Schicedte and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
