238 ARANEIDEA. 
26. Cyrene fusca, sp. n. (Tab. XX. figg. 6, 6a-c, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 8 millim. 
Hab. Costa Rica (Sarg). 
This spider differs considerably in general appearance from others of the group. It 
bears a small dorsal spine on the base of tibie iii. and iv., and there are no spines on 
patelle i. and ii. The abdomen is deep olive-brown, speckled with white, with an 
anterior marginal pale band and a postero-dorsal central pale band, the latter dilated 
on each side at its middle and also at its apex; sides and ventral area speckled with 
olive-brown. Cephalic area black, thoracic area broadly margined with black ; no bands 
of pale hairs. The vulva is very inconspicuous, consisting of a broad oval chitinous 
area, more or less emarginate behind, with a pair of small concave orifices close to the 
posterior margin. 
27. Cyrene elegans, sp.n. (Tab. XX. figg. 7, 7a, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 9 millim. 
Hab. Panama, Bugaba (Champion). 
Very similar to C. prominens in general appearance, and with all the legs spotted 
and annulated with brown. The vulva is quite distinct, however, from that of those 
species most resembling it in general aspect, though formed on the same plan as the 
vulva of C. albosignata: the posterior margin is emarginate in the middle, sinuous on 
each side; in front of this margin lie a pair of dark spots, marking convolutions of 
the oviduct, and in front of this again lies a large shallow piriform cavity, partially 
concealed by long hairs. 
28. Cyrene bicuspidata, sp. n. (Tab. XX. figg. 8, 8,6, ¢ ; 9, 9a, 2.) 
Type ¢, gynetype 2, in coll. Godman & Salvin. Total length, g 7, 2 8 millim. 
Hab. Panama, Bugaba (Champion). 
It is almost impossible to believe that the female of this species, or the male either, 
is different from C. prominens. The coloration of the abdomen is precisely the same ; 
the legs are annulate in both species, i., ii., iii., and iv. in the female, iii. and iv. in the 
male. The only differences lie in the greater length of the carapace in C. prominens, 
the absence of the dusky spot beneath the abdomen at the apex (but it is doubtful if 
this is constant), and, of course, in the vulva and palpal organs, which are quite 
distinct in structure. 
29. Cyrene delecta. (Tab. XX. figg. 10, 10a-c, ¢ ; 11, 1la, 4, 2.) 
Cyrene delecta, Peckh. Occas. Papers Nat. Hist. Soc. Wisc. iii. 1, p. 68, t. 6. figg.2a,b(¢), 
2, 2c (2) (April 1896) *; Banks, Proc. Calif. Acad. Sci. (8) i. p. 285”.
