Second pair of legs much stronger than the first, exceeding the rostrum by the length of the hand; fingers more than half as long as the palm. Length, about 21 mm.; carapace, 8 mm.; rostrum, 2 mm.; hand, 5 mm. Color: Cephalothorax and abdomen dark brownish-red, telson and tail fins white, eye- stalks and pedtincles of antennae and antennules white, flagella of antennae and antenjiules and bands on legs purple. Only one specimen, an ovigerous female, has been collected. It was obtained by the Fish Hawk and brought to the laboratory pre- served in formalin, but was not noticed until some days later. The color notes were made at once and the specimen transferred to alcohol. Within a few days a spotting or mottling of the surface began to appear, which by the end of the summer had become quite pronounced, but the spots do not have the arrangement described by has there been a suggestion of the bands of.

At no time color described by Dr. Mary J. Rathbun in G. americanum. A careful comparison of the Beaufort specimen with the two species mentioned and with G. elegans shows it to be distinct. It is probably most closely related to G. panamense. which it resembles in color pattern, and with which it agrees in length of rostrum and number of rostral teeth. It differs from all hitherto known species, however, in the arrangement of the spines at the tip of the telson. It, furthermore, differs
