NO. 2 GARTH : NEW BRACHYURAN CRABS 11 



Color in life: Carapace clear pearly gray. Numerous orange- red 

 dots along mid-line and continued on rostrum. Eye dark purplish red 

 with green highlights; a few red dots on eyestalk. Merus of ambula- 

 tories banded with similar dots. Chela with faint tint of orange along 

 upper surface. (Petersen) 



Range: Eight specimens of the species, which was encountered by 

 the 1938 expedition only, were dredged at Hood, Barrington, and 

 Daphne Minor islands, Galapagos, in depths of from 20 to 160 fathoms. 



Remarks: This species is the Pacific counterpart of the Atlantic 

 species, A. frontalis (A. Milne Edwards) (1879), from which it may 

 be distinguished by the equal lengths of the third and fourth legs, the 

 single carpal spine, and the less produced posterior margin, which is 

 devoid of a tubercle. Dr. Fenner A. Chace, Jr., has co-operated in the 

 comparison of Hancock material with specimens in the Harvard Mu- 

 seum of Comparative Zoolog}^

Plate 2, Figs. 1-4 



Type: Male, holotype, Cat. No. 382, Allan Hancock Foundation, 

 The University of Southern California, and one male and one female, 

 paratypes, from north of Hood Island, Galapagos, 20-40 fathoms; Jan- 

 uaiy 28, 1938; collected by Allan Hancock Expedition of 1938 at 

 Station 814-38. 



Measurements: Male holotype: length of carapace including ros- 

 trum 12.8 mm., width of carapace 7.9 mm., length of rostrum 2.5 mm., 

 of cheliped 14.6 mm., of first ambulatory leg 34.0 mm. Female paratype: 

 length of carapace 12.3 mm., width 4.7 mm. 



Diagnosis: Two prominent tubercles, one cardiac, one gastric; in 

 front of the latter a lesser tubercle. Palms spinulous. Rostrum acumi- 

 nate, typically bifurcate. First ambulatoiy of male two and one-half 

 times length of carapace. Postorbital spine large, laciniate ; hepatic spine 

 cylindrical. Basal antennal article spinulous at outer distal angle. 



Description: Carapace smooth, pyriform, elevations separated by 

 shallow grooves of which the gastrocardiac seems to form a constriction 

 about the body below the hepatic level. Two prominent setose tubercles 

 or spines, one cardiac and one gastric; in front of the latter a smaller 

 tubercle. Gastric region smooth, rounded, declivitous posteriorly, bearing
