COMPLETE HAIG : EASTERN PACIFIC PORCELLANIDAE 61 



and not strongly projecting beyond them; a deep median groove. Outer 

 orbital angle slightly produced into a small tooth. No epibranchial spine, 

 but usually a small tubercle or one or two minute spinules at epibranchial 

 angle. 



First movable segment of antenna with a strongly projecting, trun- 

 cate, lamellar lobe, its margin granular; second with two or three small 

 tubercles on anterior margin; third nearly smooth; flagellum with 

 short hairs. Outer maxillipeds smooth. 



Chelipeds pubescent, covered with scattered, strongly projecting coni- 

 cal tubercles. Merus with a narrow, conical, strongly projecting lobe on 

 anterior margin. Carpus pubescent, about twice as long as wide ; a small 

 rounded lobe at proximal end of anterior margin, more in the form of 

 a strongly projecting tooth in young specimens, this lobe and rest of 

 anterior margin lined with a row of strongly projecting conical tuber- 

 cles; no crest on posterior margin, latter ending distally in a long pro- 

 jection. Manus pubescent, covered with tubercles somewhat larger than 

 those on carpus ; outer margin with a broad, thick fringe of soft plumose 

 hairs, continuing to tip of pollex and around "elbow" onto distal fourth 

 of posterior margin of carpus. Dactylus with two longitudinal rows of 

 large pointed tubercles. Fingers in the two chelipeds markedly dissimilar 

 in males, less distinctly so in females and young: in one cheliped, 

 fingers meeting for entire length, and gape with pubescence sometimes 

 produced into a long, heavy tuft covering entire ventral surface of 

 dactylus; in the other cheliped, dactylus and pollex blunt and curved, 

 gaping for entire length, gape with a short pubescence. 



Walking legs flattened, thickly covered with pubescence which forms 

 anterior and posterior fringes in all segments; all segments with a few 

 scattered conical granules. Merus without spines on anterior margin, 

 but anterodistal angle sometimes spine-tipped ; legs 1 and 2 with two or 

 three spines near distal end of posterior margin, leg 3 without posterior 

 spines, inflated. 



Material examined: See Table 14. 



Measurements: Males, 3.1 to 11.1 mm; non-ovigerous females, 3.4 

 to 11.0 mm; ovigerous females, 5.4 to 10.4 mm. A type specimen was 

 reported to be 7 mm long by 6 mm wide. 



Color: In alcohol, tubercles of chelipeds tipped with red; bent tip 

 of dactyl bright red. (Lockington) Most of the specimens examined 

 were a pale orange or rust color.
