Diagnosis.—Carapace broader than long; lateral margins of pos- terior two-thirds converging posteriorly. Fronto-orbital border in adult less than half width of carapace, in small specimens half width of carapace. Branchial fm-row deeply incised. A deep crescentic furrow either side of cardiac region. Carapace liigh, in front sub- globular. Description.—Frontal teeth stout, bluntly rounded at tip. Ex- ternal angle of orbit not advanced. Tooth at branchial furrow acute, directed outward and behind a well-marked triangular Figure IZ.—Dromidia larraburei, female holotype (40475): Outline of carapace, natural size. The protuberance on the pterygostomian region, adjacent to the buccal tooth is large and smoothly rounded, not dentiform. The small tubercles on upper surface of palm are ball-shaped, not pointed. Ambulatory legs broader than in antillensis, the last two pairs shorter than in that species. Color.—In alcohol, yellowish tan, tips of chelipeds flesh color; color in life similar (Weymouth). Measurements.—Ovigerous female (41839), length of carapace 32, width mm. Range.—Monterey Bay, CaHf., to Peru and Galapagos Islands. Low tide to 60 fathoms.
