436 THE PHALANGIA AND PEDIPALPI IN WESTERN SOUTH AMERICA, 



tinct portions ; ornamented with numerous tubercles, which, posteriorly, are arranged 

 in very pronounced transverse series, also with 5 pairs of prominent spines ; the most 

 anterior pair of the latter are placed on the eye-eminence ; the second and third pairs have 

 their bases elevated; the third pair are much the largest. Eye-eminence very broad, 

 tuberculate, bifid above by a pair of diverging spines. Maxillae smoothish. Palpi nearly 

 as long as the body, rather slender, roughened by numerous tubercles, distally sub-cylin- 

 drical; their penultimate article somewhat dilated, with a pair of long, slender, very acute 

 incurved spines, and several smaller ones on each margin ; their last article smoothish, 

 dilated, with slender, very acute, prominent incurved spines on its margins. Ventral sur- 

 face and coxae of feet roughened with large numbers of tubercles ; the posterior coxae with 

 a small spine on their posterior upper angle. Posterior pair of legs roughly tuberculate 

 proximally ; tarsi 8-10 jointed, hairy, the last joint armed with 3 curved claws. (PI. 24, 

 fig. 5.) 



Remarks. — There is in the collection but a single specimen of this species, a female, I 

 believe. All of the legs are broken off except a single hind one.

Dorsum dark brown, with somewhat of an olivaceous or ferruginous tint. Cephalo- 

 thorax provided with a row of 3 small greenish tubercles on each side of its anterior 

 margin, and divided by a curved transverse line into two portions ; the anterior of the 

 surfaces thus separated, is elevated up to the position where it is crowned with two rather 

 widely separated cylindrical obtuse spines or processes, upon the exterior side of whose bases 

 the two large eyes are placed ; the bases of these processes are rather coarsely tuberculate, 

 and the general posterior slope has a pair of patches of large, somewhat greenish trans- 

 lucent tubercles: the posterior of the surfaces is divided anteriorly by a curved V-shaped 

 line, whose point runs into the first line, so that two small islets of surface are separated, 

 in the centre of each of which is an elevated transparent tubercle, similar to those of 

 the afore-mentioned patches, with some small scattered tubercles around it : posteriorly 

 to the last-mentioned line is a similar transverse one, the surface separated by which has 

 some scattered small tubercles, besides a pair of others smaller though similar to and in the 

 same line with the transparent tubercles above mentioned ; the sub-surface posterior to the 

 last-mentioned impressed line, has a very large, prominent pair of divergent robust spines 

 and minute scattered tubercles. Palpi, chestnut brown, very roughly tuberculate. Man- 

 dibles, chestnut brown, with a curved, acute, robust, short spine on the upper surface of 

 their penultimate article at the margin of the cephalothorax ; their last article robust,
