Obs. — I have considerable doubt whether these are identical with the Ja- 

 maica species, which can only be ascertained by comparison with recent 

 specimens.

This species greatly resembles S. morsitans, but differs from it in the posterior legs being 

 more slender and without elevated margins. It is also much larger. The cephalic 

 segment is small, and the basilar rather large. The posterior legs are flattened on 

 their upper surface, with the external border subacute, the internal with two spines, 

 the four anterior in two subapproximated pairs, with the fifth elongated and quadrifid. 

 The inferior surface of the basilar joint convex, with nine spines in alternating series, 

 as in S. morsitans. Preanal scale cordate, with the margin rounded. Lateral appen- 

 dages very short.

pedibus pos % tremis brevibus crassis; articulis basali secundoque marginibus elevatis:

Cephalic segment quadrate cordate ; antennae red ; basilar segment large, transverse ; man- 

 dibular tooth large j labium smooth, flat, without sutures ; dental plates short, trans- 

 verse, quadrate, with the anterior margin rounded ; teeth eight, short, obtuse, distinct. 

 Posterior pair of legs short, with the basilar and second joints equal ; flat on the superior 

 surface, with the internal margin acute, with six spinulae, the four posterior of which are 

 approximated in double series ; external margin slightly rounded, with a slightly elevated 

 border; inferior surface rounded, with nine small spines arranged in three longitudinal 

 irregular series. Lateral anal appendages very short, obtuse, with the apex bifid. Pre- 

 anal scale flat, with an impressed longitudinal line; posterior border rounded. 

 This is very like S. morsitans-, but it has an orange-coloured head and red 



antennae like S. varia and S. erythrocephata, characters which I have not
