COMPLETE HAIG: EASTERN PACIFIC PORCELLANIDAE 89 



Description: Carapace covered with plications and fine granules, 

 nearly smooth in some specimens; regions distinct. Front triangular, 

 with a deep median sulcus; no supraocular spine; inner orbital angle 

 not produced. Outer orbital angle not produced. No epibranchial spine. 

 Carapace naked or lightly pubescent, distinctly hairy in some speci- 

 mens. 



First movable segment of antenna lightly granular, with a strongly 

 projecting lobe on anterior margin ; second and third lightly granular ; 

 flagellum variable, with hairs absent or vestigial in some specimens, 

 rather long in others. Outer maxillipeds lightly rugose. 



Chelipeds finely granular. Merus with a strongly projecting gran- 

 ular lobe on anterior margin. Carpus about twice as long as wide ; a 

 small lobe at proximal end occupying about one-fourth of anterior 

 margin, anterior and posterior margins otherwise subparallel ; a low 

 longitudinal crest on dorsal surface, obsolescent in some specimens; 

 granules along posterior margin enlarged and forming a low crest, end- 

 ing distally in a sharp tooth ; surface covered with short hairs. Manus 

 usually a little smoother than carpus, lightly pubescent in young speci- 

 mens; outer margin thin. Gape with a thick pubescence, produced into 

 a long tuft at proximal end of fingers. 



Walking legs rugose ; merus unarmed, that of leg 3 not inflated ; 

 merus with plumose and non-plumose hairs, other segments with tufts 

 of setae. 



Material examined: See Table 25. 



Measurements: Males, 3.0 to 15.4 mm; non-ovigerous females, 3.9 

 to 10.8 mm; ovigerous females, 4.8 to 11.3 mm. A female, the largest 

 of his series, was stated by Glassell to be 12.1 mm in length. The male 

 holotype measures 11.4 by 11.0 mm, the ovigerous female allotype 10.1 

 by 10.5 mm. 



Color: "Ground color of carapace dull orange, with striations and 

 numerous spots of very pale greenish white. Margins pale lavender, 

 which becomes darker toward and including the frontal region, where 

 it is dark dusky purple. Antennal peduncles same color as carapace, 

 flagellum ochre with purple edges. Basal segments of maxilliped striated 

 with dull orange and brilliant green; palp brilliant orange. Ground 

 color of carpus green, numerous granulations reddish brown, almost 

 obscuring ground color; hand and finger same color but slightly darker, 

 underside of finger pale, bright, turquoise blue ; undersurface of hand 

 much lighter, with green prominent. Merus and carpus of ambulatory
