S . Body. — Tlie shape of the body of this new species is 

 very like that of Z. rohusta, Sor., as figured by Sorensen, the 

 cephalothoracic part of it being much narrower than and not 

 nearly so high as the abdominal part. 



Scutum longer than the patella + the tibia of the fourth 

 leg. It has five transverse grooves; the first one, which is 

 well defined and procurved, forms the boundary between the 

 cephalothoracic and abdominal parts of the scutum ; the 

 other grooves are not so distinct, the one between the first 

 and second areas of the abdominal part being faint. First 

 abdominal area large, but its length (when measured along 

 the median line) is very much less than that of the cephalo- 

 thoracic part. Except for three or four rather incotispicuous 

 granules on each side of the anterior margin and for one or 

 two lateral granules, the surface of the cephalothoracic part 

 is quite smooth. Numerous granules are present on the first 

 abdominal area and a rather narrow transverse band of them 

 is present on each of the three following areas ; the granules 

 of which these bands are composed are not very regularly 

 arranged, but they are usually about two deep. The last 

 abdominal area has fewer granules on its surface than the 

 other areas, and for the greater part of its width they are 

 arranged in a single series only ; like those of the penultimate 

 area, they are sharply pointed and directed backwards. 

 There is also a longitudinal series of granules on each side of 

 the scutum. Ocular tubercle situated near the anterior 

 margin. It is elongated transversely, being considerably 

 ■wider than long, and has no large processes of any kind on 

 its surface, but is furnished with a number of granules, 

 which are not ai'ranged in a regular manner. 



Free dorsal segments. — The two anterior of the free dorsal 

 segments each have a single transverse series of granules, 

 similar to that on the last area (posterior margin) of the 

 scutum ; on the third free segment the granules are more 

 numerous and less regular in arrangement and are mostly 

 ranged about two deep. The fourth free dorsal segment has 

 numerous granules and they are not arranged in series. 



Ventral surface. — Fourth coxa very much wider than the 

 others. There are a number of distinct granules on the 

 ventral surface of the first coxa, but only obsolete granules
