COMPLETE HAIG: EASTERN PACIFIC PORCELLANIDAE 191 



Lectotype: Ovigerous female, 6.7 mm in length by 4.4 mm in width, 

 in Paris Museum, labelled '^Porcellana transversilineata Lockington. 

 Californie — Lockington 6-99 (Type)." This specimen, one of two so 

 labelled, is hereby selected as the lectotype at the request of Mr, Jacques 

 Forest. 



Diagnosis: Carapace about one and a half times as long as broad, 

 with distinct transverse striations; basal segment of antenna with a 

 broad inward projection and a small forward projection, the latter nar- 

 rowly separating movable segments from orbit; flagellum shorter than 

 carapace, without hairs; dactylus of walking leg 3 normal. 



Description: Carapace about one and a half times as long as broad, 

 covered with distinct transverse striations broken up into large flat- 

 tened granules anteriorly; protogastric lobes accentuated, regions other- 

 wise not distinct ; anterior regions with long, scattered setae, hooked 

 at their tips. Front divided into three long slender teeth, median one 

 the longest ; margins of median tooth and inner margins of lateral teeth 

 fringed with short plumose hairs. Hepatic and epibranchial spines large, 

 distinct, separated by a deep U- or V-shaped notch. 



Basal segment of antenna with a broad inward projection, almost 

 entirely visible in dorsal view; a small forward projection, narrowly 

 separating movable segments from orbit ; first and second movable seg- 

 ments broader than eyestalk, but not massive and filling concavity be- 

 tween outer orbital angle and hepatic spine ; third small ; flagellum 

 shorter than carapace, naked. Outer maxillipeds nearly smooth or cov- 

 ered with small flattened granules; sternum truncate anteriorly. 



Chelipeds covered with small, flattened granules and long, scattered 

 setae, hooked at their tips. Merus with a long, narrow tooth at distal 

 end of anterior margin. Carpus short and stout, with one to four nar- 

 row, widely separated spines on anterior margin. Manus flattened, 

 outer margin with a row of spines, the latter more pronounced in 

 males, sometimes obsolescent in females. Fingers meeting for entire 

 length or slightly gaping. 



Walking legs rather short and stout, rugose ; all segments with tufts 

 and fringes of long non-plumose setae. Propodus subcylindrical. Dactylus 

 with a row of small tubercles on posterior margin in place of movable 

 spinules. 



Telson of abdomen much longer than broad. 



Material examined: See Table 58. 



Measurements: Males, 5.1 to 8.0 mm; non-ovigerous females, 5.8
