GAYENNA. 
Gayenna, Nicolet, in Gay’s Hist. fis. y polit. de Chile, Zool. iii. p. 450 (1849). 
Type G. americana, Nicolet. Chili. | 
I do not know this genus; but according to M. Simon the spiracular rima is situated 
towards the spinners, and the anterior row of eyes is straight. ‘Two species from 
Mexico have been referred to it by Mr. N. Banks. 
1. Gayenna orizaba. 
Gayenna orizaba, Banks, Proc. Calif. Acad. Sci. (3) i. p. 223, t. 18. fig. 37°.

Gayenna minuta, Banks, Proc. Calif. Acad. Sci. (3) i. p. 224, t. 18. fig. 32°.

Pelayo, O. P.-Cambridge, Biol. Centr.-Amer., Arachn. Aran. i. p. 194 (1896). 
ype P. letus, O. P.-Cambr. Costa Rica. 
Differs from Gayenna (see Simon’s characterization of this genus) in the recurved 
posterior row of eyes. 
1. Pelayo letus. 
Pelayo letus, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran, i. p. 194, t. 24. figg. 7, 7a-f'(3)’: 
Type, dg, in coll. Godman & Salvin. Total length 4°25 millim. 
Hab. Costa Rica (Sarg '). 
Fam. CTENIDE. 
Eyes eight, situated in three or four transverse rows of 2,4,2 or 2,2,2,2 or 4,2,2. Other characters 
similar to those of the Clubionide. Legs normal. 
The Ctenide are represented in Central America and other tropical regions by 
numerous genera and a very large number of species, all of which are characterized by an 
eye-formula quite peculiar to them amongst two-clawed forms, though it crops up again 
amongst the two-clawed cribellate and amongst the three-clawed forms. Except with 
respect to their eye-formula, they are simply Clubionids. The species included in 
the family under the generic name Ctenus embrace a large number of forms varying 
considerably in size and coloration. The giants of tropical America and Africa measure 
as much as three inches in expanse of leg, while numbers of comparatively minute forms 
are found in both the western and eastern tropical regions. There seem to be no
