commissural pores 8-19 in specimens 23-40 mm SL; preopercular 

 series of pores with at least 5 pairs or multiples of pores included in 

 the series ; 1 pore before each anterior nostril ; lateral line terminating 

 on side of body in area below and between dorsal rays 2 and 4 ; ventral 

 margin of upper lip crenulate on lateral thirds, entire on middle third; 

 lip crenulae number 6-10 on each side. 



Proportional measurements: Only one specimen, female, 35.3 mm 

 SL, was in sufficiently good condition to allow measurement. Meas- 

 urements as percent SL on this specimen: HL 23.8; OL 6.5; OCL 4.0; 

 NCL 4.5; DS3 10.2; DRl 12.5; PECL 23.5; PELL 17.3; CL 21.5. 



Of the nine subadult-adult specimens available, only one was a 

 male, approximately 40 mm SL and immature. 



Color pattern of preserved specimens. — In specimens with 

 the most developed color pattern there are Qji pairs of pale dusky, 

 vertical bands on the body (half pair on side beneath anterior dorsal 

 spines). The bands are darkest in their midportions. Ventrally the 

 bands fail to reach the ventral body contour. Dorsally the bands 

 extend onto the dorsal fin where they intensify considerably and take 

 a dorsoposterior direction. On the midside between the band pairs, 

 some specimens show indications of pearly white spots. The head, 

 posterior to the eye, bears as its darkest markings two short, more or 

 less vertical stripes separated by a broader pale area. Ventral to the 

 stripes, some specimens bear a short pearly white horizontal stripe or 

 band. The upper lip is variably dusky, sometimes bearing several 

 irregular bands extending onto the snout. The underside of the head 

 is uniformly dusky. 



The anal fin (for dorsal fin, see above) is evenly dusky anteriorly, 

 grading darker distally. Posteriorly, the fin is dusky with included 

 pale spots. The pectoral fin is dusky, darkest on the ventralmost 

 rays. The pelvic fins are dusky. The caudal fin bears three or four 

 dark vertical stripes composed of series of dark spots overlying the 

 rays. 



Nomenclature. — Fowler (1932a) described Gvffordella corneliae 

 (new genus, new species, monotypic) from a larval (ophioblennius) 

 specimen (and 10 larval paratypes) from the Marquesas Islands. The 

 holotype (USNM 91821), approximately 17 mm SL, has 13 dorsal 

 spines, 13 segmented dorsal rays (in four countable paratypes, 14, 15, 

 15, and 15 rays), 16 segmented anal rays (the last split to the base), 

 14 pectoral rays, 1,4 pelvic rays, a notch between the spinous and soft 

 dorsal fins, nasal, nuchal, and supraorbital cirri (one each on each 

 side), a pair of pores included in the circumorbital series (left side 

 only), and three predorsal commissural pores. This combination of 

 characters leaves no doubt in my mind that the holotype is a species 

 of Entomacrodus {Giffordella is therefore a junior generic synonym of
