CORINNA. ral 
Palpus: patella very short, convex, scarcely longer than. broad. Tibia very broad, its apex above produced 
into a broad, blunt point, concave beneath, directed over the base of the tarsus: it bears two large lateral 
spurs on the outer side; the upper one more or less simple, rounded, convex, bicuspid, the upper branch 
very convex, terminating in a short blunt black point, concave beneath; the lower spur has a large 
concave area at its base on the inner side, whence springs a pale elongate slender process, directed 
forwards. Above this area lies on the inner side a shining chitinous convex piece, concave within. The 
apex of the spur is bifid, the inner branch uncate, the outer longer and straight. 
Bulb bearing two dark spurs at its apex and a long slender membranous process. The larger spur is very 
broad (almost the whole width of the bulb) at the base, narrowing to a point (seen from above), but (seen 
from the inner side) is concave and broad at the apex. The smaller spur, lying between the former and 
the membranous process, is shorter and also broader when seen from the inner side. 
The tarsus is produced into a very stout sinuous process at its base on the outer side. (This last and the two 
tibial spurs are very difficult to see, since they all lie closely together.) Lower margin of fang-groove 
with five subequal teeth.

@. Colour and structure as in C. mucronata, but the carapace and mandibles are blacker, and the legs darker 
orange-brown. Carapace and mandibles less strongly rugulose-impunctate. Eyes grouped more closely, 
anteriors almost in contact. Lower margin of fang-groove with five teeth. Central anterior eyes only 
very slightly larger than laterals; clypeus just over one diameter of an anterior central eye. Sternum 
very slightly granulose anteriorly ; legs smooth. ‘Tibia i. with three pairs of spines beneath, no apical 
pair; ii. with three spines on the outer side. Protarsus i. with two pairs of spines and no apical spine. 
Vulva exceedingly similar to that of C. nava; consisting of two oval concavities divided by a narrow chitinous 
bridge connecting the anterior and posterior margins; the anterior and lateral margins are rugulose and 
impunctate, the posterior margin broader and smooth, shining in the middle. There is no-convex ridge 
running from behind into each concavity.

14. Corinna retusa, sp.n. (Tab. V. figg. 13, 13 a, 2 .)

Total length 9 millim. Carap. 4:25x3. Sternum 2x1°75. Pat.+tib. i.4; iil, 3:25; iv. 4. Prot.i. 2;

Q. Carapace and mandibles deep mahogany-brown, finely granulose. Sternum and legs paler mahogany-brown, 
granulose. Abdomen clay-yellow, its anterior margin and a shoulder-spot brown; also a brown, lanceolate, 
central anterior dorsal band, with a lateral line on each side of its broadest part, becoming suddenly 
narrowed to a thin line posteriorly, with a longer transverse lateral line on each side at its extremity, 
which is situated at the middle of the abdomen. The posterior dorsal and lateral areas are dusky brown. 
Structure similar to that of C. luctuosa, except that the coxe of the legs are only very slightly and all the other 
segments, except the femora, less closely granulose. The legs and abdomen are clothed with much 
longer hairs and spines. Anterior row of eyes very strongly procurved. Clypeus equal to one and a half 
diameters of an anterior central eye. Lower margin of fang-groove with six'tceth. Tibia i. with five pairs 
of long spines; no apical pair. Tibia ii. with four spines on the outer side, three on the inner side. 
Protarsi i. and ii. with two pairs of spines beneath; no apical spine. 
Vulva consisting of a circular convex area, somewhat bilobate in the centre, having a large subtriangular 
transverse cavity about the middle, and another smaller one just in front of it. 
Hab. Guatemata (Sarg).
