LYCOCTENUS. 
Lycoctenus, F. P.-Cambridge, Ann. & Mag. Nat. Hist. (6) xix. p. 95 (1897). 
Type L. brunneus, F. P.-Cambridge. Lower Amazons. 
Eye-formula “ ctenoid,” second row procurved ; lateral anteriors midway between the central and lateral 
posteriors. Lower margin of the fang-groove with four stout teeth (sometimes three only). Tibie i. 
and ii. with 2—2—-2—-2 spines beneath ; protarsi i. and ii. with 2—2—2 spines and a single, central, 
apical spine, and iii. and iv. with two apical spines, beneath. Protarsi and tarsi i. and ii. thickly 
scopulate beneath; tarsi ili. and iv. alone scopulate, and also with a double row of short spines 
beneath. 
This genus is possibly synonymous with Ancylometes, Bertkau.

DOLOMEDES. 
Dolomedes, Latreille, Nouv. Dict. xxiv. p. 185, column 2, line 82 (1804). 
Type D. marginatus (De Geer) = fimbriatus, Clerck. Europe. 
I have not seen any examples of this genus from Central America, but the spiders 
here described under Lycoctenus are very similar in general appearance to the type of 
Dolomedes, though the eye-formula is different.

THAUMASIA. 
Thaumasia, Perty, Del. Anim. Art. Bras. p. 192 (1833). 
Type 7. senilis, Perty. Brazil. 
Anterior row of eyes straight or slightly procurved, centrals much larger, almost in contact with each other 
and with the laterals ; posterior centrals less than a diameter apart, further from the laterals. Clypeus 
varying in size from three times that of an anterior central eye to less than a diameter of one. Both 
margins of the fang-groove tridentate, the posterior tooth on the lower margin more remote from the 
others. Tibie i. and ii. with 2—2—2—2 spines beneath, besides laterals on each side, no small apical
