trunk, one spot being placed immediately in front of tlie 

 other ; the thorns of the scutum are not darker than its 

 surface. 



Measurements in mm. — Length of trunk 3*75, of scutum 

 3-25, of fourth leer 25. 



Material. — A single male specimen from Batjan [Dr. W. 

 K'dkentlial). 



Ibalonrus kuehentliali, sp. n. 



Very closely allied to 7. quadriguttatns, sp, n.,but differin^r 

 in the following details of structure and coloration : — 



Scutum armed with two pairs of long thorns, which 

 correspond to the first and third pairs of /. guadriguttatus, 

 but the second pair of very short thorns, which are present 

 in that species, are absent in /. kiiekenthali. A little granule 

 is placed midway between the eyes. A pair of little granules 

 is present on the part of the scutum which apparently corre- 

 sponds to the first abdominal area and there are three trans- 

 veise series, each of four little granules, on the parts of the 

 scutum apparently corresponding to the second, third, and 

 fifth (last) abdominal areas of the scutum. As in 7. qnadri- 

 quttatus oidy the last transverse groove is distinct. 



Ventral surface. — The granules on coxae 2—4 are more 

 numerous and more distinct in this species than is the case 

 in I. (jnadriguttatus. 



Cheh'cera and palp precisely similar in structure to those 

 of /. quad rig uttatus. The femur of the first leg is more 

 coarsely granular than in that species. Number of tarsal 

 segments 4, 12, 6, 5. 



Colour. — Body pale brown, but its spines are very dark 

 brown. There are no golden spots on the dorsal surface. 

 Chelicera slightly infuscated ; the palp pale; legs rather 

 dark brownish. 



Measurements in mm. — Length of trunk 3"75, of scutum 

 3"5, of fourth leg 26. 



Material. — A single male example from Batjan, collected 

 by Dr. W. Kiikentlial. 



Remarks. — The body and legs of this species are darker 

 in tint (browner) than is the case in /. quadrig uttatus, and 

 there are no golden spots on the scutum ; moreover, the four 

 thorns are much darker than the surface of the scutum. 

 Besides this difference in coloration there are the slight 

 strttctural differences noted above. 



The most striking feature of these two new species of 

 Ibalvnius is the absence of the thorn which is usually present
