Smaller chela about one-third the size of its mate, somewhat compressed but otherwise similarly constructed. Third, fourth, and fifth legs with short, conical dactylus. Telson narrow, its sides uniformly convergent to the small rounded tip, which bears four slender spines; there is also a spine on each margin near the middle. Length of body, i6 mm., cara- pace, 7 mm., large claw, lo mm. Color, pellucid, milky white. Egg masses light bluish-green. The integument is so transparent that the color of the internal organs is plainly visible. Three specimens of this little shrimp, 2 females and i male, were obtained August i, 1914, on the fish- ing banks about 20 miles off Beau- fort Inlet. Another series of 8 or 10 specimens was collected July 20, 1915. In both cases the animals were found in the canals of a large sponge in com- pany â ivith Synalpheus longicarpus and 5. townsendi, to which they bear a striking superficial resemblance. When disturbed or, especially, when dropped into alcohol, they are able to make a snapping sound with the large chela quite as loud as that made by one of the true snapping Fig. 13.âCoraUiocaris, wilsoni, cf X4M. a. Carapace, lateral view; b, telsoa and uropods; c. large chela; outer sur- face; d, fingers of large chela from above; e, small chiliped; /. right leg of first pair; o. antennule. The species has been dedicated to Dr. H. V. Wilson, of the University of North Carolina, for many years an investigator at the Beatifort station, at one time its director, a well-known authority on sponges, and the one to whom the imdertaking of this paper on the decapod crustaceans is largely due. Family GNATHOPHYLLIDAE. Caridea having the first two pairs of legs chelate, the first pair smaller than the second, the carpus of the second pair not subdivided, the rostrum
