426 AUGUSTA EüCKER, 



the chelicerae^i have been described so miniitelj^ by Dr. Hansen 

 and since they do not possess points, apart from those dwelt on 

 already. cliaracteristic of the species, unless it be in the relative 

 proportious of the joints (which I doubt), I did not g-ive any space 

 to them in enumerating the characters of the adult K. ivheeJeri. 

 Every thing said about the appendages in the last stage represents 

 the exact condition found in the adnlt. 

 First pair of Legs. 



1. The second tarsal Joint has one tactile hair on its upper 

 surface and slightly posterior. 



2. The foiirth metatarsus Joint likewise is in possession of one 

 of these organs on its posterior surface. 



3. The second metatarsus holds two of these organs on the the 

 posterior surface, one being a little more ventrally situated than its 

 fellow. 



4. The flrst metatarsus advances one step beyond stage two 

 and two steps beyond the first stage and carries two of these long 

 tactile hairs on its upper surface. 



5. The tibia has one tactile hair in its usual place. 



6. The outer surface of the third metatarsus has the large hollow 

 seta near its distal end. 



7. Bifurcated hairs are preseut on the metatarsus and tarsus. 



8. The metatarsus of the last leg has the stiff hollow seta. 



A b d m e n. The hing sacs are present on the fourth, fifth and 

 sixth Segments. Over the appertures of these sacs three plumulose 

 setae (a portion of the segmental whorl) project, The third and 

 fourth Segments which in the adult possess three pairs of long setae, 

 situated between the hing sacs, at this stage have oiily a Single 

 pair. The sixth segment presents the same appearance as is seen 

 in the adult except there seems not to be as much of a grouping 

 of the four pairs of setae in the region anterior to the hing sacs. 



Reproductive Appendages. In the male the prolonged 

 ventral projection of the second segment has become split at the 

 tip dorso-ventrally and then divided symmetrically into a right and 

 left portion. This gives the appearance at this stage of two pairs 



1 ) I believe that Dr. Hansen who was the first to point out the two 

 kinds of teeth on the fixed proximal Joint of the chelicera is entirely 

 nustaken as to the origin of the smaller teeth. These denticles are not 

 branches of the teeth as he has figured them but arise from a distinct 

 outer ridge.
