upper the anterior two teeth are large and subequal, as large, 
in fact, as the fourth—the third, fifth, and following ones 
being small. 
Palp with its protarsus studded below with two series of 
longish spines. 
Measurements in millimetres.—Total length 16; width of 
head 4, length 3; length of mandible 5:3, of palp 12, its 
protarsus and tarsus 4, of fourth leg 18. 
A single female example from Socotra (J. B. Balfour). 
Genus CLEOBIS. 
Cleobis gryllipes (Gervais). 
Galeodes gryllipes, Gervais, L’Institute, 1842, p. 76; Ins, Apt. iii

In his description of this species Gervais wrongly asserts 
its locality to be Martinique. ‘The type specimen preserved 
in this Museum, labelled, apparently, by Gervais himself and 
agreeing accurately with his description, bears a ticket on 
which Jamaica is distinctly written. In the British Museum 
there is no example of Solifugee belonging to this or any 
other genus from Martinique. 
The type of the species in question is a male, and it may 
be recognized from both males and females of the other species 
known to me by the presence of two minor teeth between the 
two large teeth on the lower fang of the mandible. 
Cleobis Gervaisit, sp. n. 
Colour. Cephalic plate and mandibles entirely pale yellow ; 
palpi with femora, proximal end of tibia, and proximal half 
of protarsus flavous, the rest fuscous; legs, with the excep- 
tion of the basal segments, infuscate, the anterior pair paler 
than the posterior (fourth pair missing in type); free thoracic 
segments and abdomen fuscous above. 
Ocular tubercle represented merely by a slight prominence, 
projecting anteriorly between the eyes, which look forwards, 
upwards, and outwards, the space between them about equal 
to a diameter. 
Mandibles with a distinct crest at the base of the upper 
fang; the first and second teeth about as large as the fourth, 
the third small; in the lower jaw there is one small tooth 
between the two large ones. 
Palp without spines, except for a few small ones on the 
inner side of the lower surface of the protarsus.
