Diagnosis. — Extreme length of carapace about two-thirds extreme 

 breadth; posterior teeth of lateral wing obtuse, blunt; a concave longi- 

 tudinal strip on lower half of outer surface of manus. 



Description. — Carapace, outer surface of winglike expansion of 

 arm, upper surface of wrist, and outer surface of palm covered with 

 coarse granules, more closely placed on anterior than on posterior 

 half of carapace, and forming several longitudinal rows of flattened 

 tubercles. Anterolateral border crenulate and granulate; posterior 

 border, exclusive of wings, subentire with beaded edge. Wings well 

 developed, with seven strong teeth with beaded edges, three behind 

 and three in front of posterolateral tooth. Pterygostomian regions 

 thickly covered with hair. Front with a large notch, projecting little 

 beyond orbits. Endostomial septum extends forward in a strong 

 tooth not reaching level of front. The winglike expansion at end of arm 

 is conspicuously 4-lobed ; the crest of palm is 8- or 9-toothed; its outer 

 face has several large tubercles and a laminate inferior proximal spine. 



Color. — Ground of carapace smoke-gray behind, shading to drabbish 

 mottled with white, over greater part of carapace; color pattern 

 Indian purple in interlacing bands on anterior half, obliquely longi- 

 tudinal stripes on posterior half. Ground of exposed surface of cheli- 

 peds more of a heliotrope purple becoming almost white on lower 

 half of palm and on fingers. Stripings of Indian purple on merus, 

 carpus and upper part of proximal end of palm; two distant round 

 spots of same color above middle of palm; spots and patches of sulphur 

 yellow on teeth and tubercles of upper half. This same yellow is 

 mixed with the background of merus and carpus and slightly so with 

 that of carapace. Two or three cadmium orange spots near base of 

 dactylus, a few spots near articulation of palm and wrist. A dragon's 

 blood red covers greater part of inner surface of cheliped, the pter}^- 

 gostomian regions, the anterior surface of first ambulatory leg and a 

 small part of second leg. Remainder of ambulatory legs, lower face 

 of arm, also abdomen and sternum whitish. (R. L. Barney.) 



Measurements. — Female, extreme length of carapace 80, width at 

 sinus just in front of wings 105, greatest width of carapace 118 mm. 



Range. — Southeastern Massachusetts to Brazil; Bermuda; Cape of 

 Good Hope (Miers); perhaps Indian Ocean. Surface to 40 fathoms; 

 125 exceptional. 



Material examined. — See table 65, pages 200-204.
