566 OPILIONES. 
13. Erginus tricristatus, sp.n. (Tab. LIII. figg. 7, 7 a-c, ¢ .) 
Type, ¢, in coll. Godman & Salvin, Total length 6 millim. (excl. mand.); femur iv. 5 millim. 
General characters similar to those of E. pectinigerus. Eye-tumulus with a crest of minute tubercles on each 
side above the eye. Spines on the third tergal segment moderately long, about as long as the space 
separating them at their base. Tarsal segments, i. 6, the three basals slightly enlarged ; ii. ? (missing) ; 
iii. 8; iv. 9. Legs similar to those of the above-named species, except that the warts beneath femora i. 
and ii, are more minute, much shorter beneath femur iii., and very minute beneath tibia iii. 
Femur iv. with a median dorsal series of 10 or 11 long (longer than the diameter of the segment), basally 
coalescent, apically free, denticles, their apices strongly and abruptly recurved; with an external inferior 
median series of longer, separate, slightly recurved denticles, the distal denticle more remote; and an 
internal inferior median series of 8 long separate (sometimes a few coalescent) denticles, the distal 4 or 5 
recurved, the basal three straighter, apically divergent, numbers 2 and 3 being much longer than the 
rest. Doubtless these details vary in different individuals. 
Colour. Body ochre-brown; legs paler, protarsi annulated with faint, narrow, paler bands. Prosoma with a 
large marginal blotch of filigreed yellow, extending on to the dorsal scutum, breaking off about the 
middle, with a fine extreme marginal yellow line. The dorsal scutum has a dotted blotch in the middle, 
while the third segment is margined posteriorly with a filigreed band. 
Hab. Guatemata, Tecpan (Stoll). 
14. Erginus clavipes, sp.n. (Tab. LIII. figg. 8, 84, 3.) 
Type, ¢, in coll. Godman & Salvin. Total length 5 millim. (excl. mand.). 
General characters similar to those of EZ. pectinigerus, but otherwise nearly allied to EZ. simplicipes. Tarsal 
segments, i. 6; ii. 18; iii. 8; iv. 9. Femur iv. basaily dilate, apically with an internal attenuate, 
inferior, slightly sinuous series of 10-12 separate denticles, not basally coalescent, subequal in length, 
about as long as the diameter of the segment, extending along the basal two-thirds; also an inferior 
apical series of 5 denticles, being the apical tubercles of a row lying adjacent to the first-named series. 
There are also two external inferior rows of small tubercles, and an irregular dorsal double series of 
denticles, more numerous and longer than in E. simplicipes. 
Colour. Body unicolorous dull olive-brown ; legs paler, femur iv. reddish-ochre. 
Hab. Guatemata, Cubilguitz (Sarg). 
15. Erginus erectispinus, sp. n. (Tab. LIII. figg. 9, 9a, b, 3.) 
Type ¢, gynetype 2, in coll, Godman & Salvin. Total length, ¢ 6, 9 5 millim. (excl. mand.). 
3. General characters similar to those of E. pectinigerus, except that the tubercles over the eyes are more 
conspicuous. Tarsal segments, i. 6; ii. 11; iii. 8; iv. 9. Mandible: basal segment almost entirely 
smooth, without tubercles ; movable digit about three-fourths the length of the dilate basal portion, with 
a large basal tooth and an apical serrate carina; fixed digit with an apical serrate carina. The spines 
on the tergal third segment are much longer than in the allied species. 
Legs similar to those of EH. pectinigerus and E. serratipes, but with the armature of femur iv. different. The 
latter with an inner inferior series of 11 or 12 short denticles, the longest scarcely equalling the diameter 
of the segment; graduated in length, the central 6 being the longer, the series occupying a space just 
below the middle of the segment, separate, not basally coalescent. There is no dorsal series of denticles, 
small granules only being present. The external inferior series consists of about 21 denticles, nearly all 
more or less coalescent basally ; the longest slightly more than the diameter of the segment; the basal 
denticle longer, conspicuously deflected upwards out of the plane of the rest of the series; the whole 
series extending from near the base almost to the apex of the segment. 
Colour. Body umber-brown ; legs pale reddish-ochre. The prosoma has a yellow filigreed marginal band, 
continuing in the form of scallops, limiting laterally segments 1, 2, and 3 of the dorsal -scutum and the
