74 Mr. F. O. P. Cambridge on Cleniform Spiders 



dinfil, lanceolate band. Tibial spur of 

 pedipalp lonorer than broad, directed 

 forwards, obliquely truucate at apex, 

 simple at base.} 



a. Size much larger, 17 mm. Abdomen 



uuicolorous above C. rectipes, sp. n. 



b. Size much smaller, 7"o mm. Abdomen 



■with pale band above - C. minimum, sp. n. 



ii. Length of carapace less than patella and 

 tibia iii. (Abdomen with pale central 

 line or scalloped band above.) 

 a. Protarsus iv. quite straight. 



1. Abdomen with central black band 



below. Tibial spur of pedipalp 

 short, directed forwards, very "oroad 

 at apex, as broad as long ; lower 

 anterior angle sharp. Central lobe of 

 palpal organs small, as long as broad. 

 Tarsus of pedipalp without spur 

 behind C. iiiyritus, sp. n. 



2. Abdomen unicoloroiis brown below. 



Tibial spur of pedipalp short, blunt, 

 rounded at apex, set obliquely to 

 axis of joint. Central palpal lobe 

 large, much longer than broad. Tar- 

 sus of pedipalp with spur at base 



behind C. longipes, Keys. 



I. Protarsus iv. slightly sinuous. 



1. Size larger. 15'5 mm. Tibial spur 



twice as long as breadth of base, 

 directed forwards ; (apex acute). 

 Apical tliird of protarsus iv. con- 

 cave on inner side C. spiculus, sp. n.* 



2. Size smaller, 10-5 mm. Tibial spur 



as long as iDreadth of base, directed 

 forwards, deeply emarginate on 

 lower side ; (apex acute) C. planifyes, sp. n.* 



* The characters enclosed in brackets are not intended to alternate 

 with others in the table, but merely to serve ns a further clue to the 

 identity of the form. 



C spiculus and plauipes should more properly, by the form of protarsus 

 iv. and the tibial spur, fall into section B, but the eye-position brings 

 them into section A. All the above species (curvipen I cannot answer 

 for, since I have not seen the ty]>e) can be readily se])arated also by the 

 character of the central lobe and marginal spine of the pulpal organs. 

 These characters unfortunately do not always ht in with those furnished 

 in the above table. 



I am unwilling to tabulate the characters of faniatns, parvus, and 

 velox, for they a]ipear to stand somewhat apart from anv of the forms in- 

 cluded above. The former may readily be recognized by the compara- 

 tivelv short legs, small size, and quadrate tibia of pedipalp, a.>< long as 

 broad ; tibial spur long, curved, blunt, directed outwards and forwards, 

 recurved at apex. Velox may be instantly recognized by the short spur 

 beneath coxa iv. ; excepting for the eye-formula, it appears to come near 

 C planipes; its posterior protarsi are straight, as also are those of 

 tceniatus.
