bb. Second lateral tooth absent or fused with first; 

 outer surface of hand rough with large beadlike

Micropanope sculptipes Stimpson, 1871a, p. 140. — Rathbun, 

 1930a, p. 428, pi. 178, figs. 1-3 (rev.). 



Recognition characters. — Carapace naked, dis- 

 tinctly areolated; anterior and anterolateral re- 

 gions somewhat roughened in front with small, 

 sharp, toothlike tubercles partially disposed in 

 lines. Anterolateral teeth sharp, denticulate, fifth 

 (last) obsolescent, first and second almost entirely 

 fused. Frontal lobes abruptly deflexed, with con- 

 vex outline; margin thin, minutely crenulate, with 

 slight furrow above it. A small tubercle on sub- 

 hepatic region below second anterolateral tooth. 



Chelipeds granulate above; carpus with gran- 

 ules arranged more or less in raised reticulated 

 rugae, inner margin denticulate and with a sharp 

 spine; hand with double denticulate crest above 

 and with minute granules on outer surface show- 

 ing tendency to arrangement in rows, becoming 

 obsolete in distal lower half of major chela, upper 

 part of inner surface granulate ; fingers grooved, 

 with a thin superior crest on dactyls. Walking 

 legs with minute spines above forming two rows 

 on carpus. 



Measurements. — Carapace: male, length, 4 

 mm. ; width, 6 mm. 



Habitat. — Fifteen to 101 fathoms. 



Type locality. — Florida Keys. 

 Known range. — South Carolina to Port 

 Aransas, Tex. ; West Indies to Barbados.

Figure 176. — Micropanope xanthiformis (Milne Edwards). 

 Animal in dorsal view, walking legs of left side not 

 shown, 5 mm. indicated. 



Recognition characters. — Carapace depressed, 

 regions well defined, with depressed coarse granu- 

 lations on anterior and anterolateral portions, an 

 oblique ridge on hepatic region. Five antero- 

 lateral teeth with granulate margins ; second tooth 

 small, blunt, obsolescent in young but consider- 

 ably larger than first in adults; third and fourth 

 teeth large, acute; fifth tooth small and pointed. 

 Front slightly deflexed, shallow, lobes separated 

 by a narrow fissure ; margin sinuous, outer corner 

 rectangular. A slight subhepatic elevation formed 

 by a number of granules. 



Chelipeds rugose with coarser granules than on 

 carapace ; merus with a row of spines above ; car- 

 pus with a deep distal groove and two inner 

 spines, one above other, upper one largest. Chelae 

 roughened proximally and on upper portion, 

 roughness more extensive on minor chela; fingers 

 deeply grooved, major dactyl with large basal 

 tooth. Walking legs long, slender; merus with 

 row of spines above, other articles spinulose. 



Measurements. — Carapace: male, length, 7 

 mm. ; width, 10 mm. 



Color. — "Anterior portion of carapace light 

 yellowish orange. Fingers of major chela brown- 

 ish black, of minor chela black. Spines and tu-
