terior external angle elongated ; teeth six, large, black, triangular and acute, with the 

 margins slightly serrated. Posterior pair of legs rather short, with the basilar joint 

 longer than the second, and the superior surface convex, with five large, acute, black 

 spines on the internal superior margin, arranged in two alternating series, the apical 

 spine simple. Inferior surface rounded, with six large, acute and slightly curved 

 spines, arranged in two longitudinal series, three on the outer margin and two on the 

 inner, with the sixth near the median line of the joint, between the two series. Lateral 

 anal appendages much elongated and pointed, with the margin rounded, and one spine 

 on the external surface, near the apex, which is bifid ; the posterior superior margin a 

 little compressed, with three spinous tubercles. Preanal scale quadrate, deeply emar- 

 ginated, with a longitudinal sulcus. 



This is an exceedingly interesting and well-marked species, although it very 

 much resembles Scolopendra middens. B'lt it is easily distinguished by the 

 large size of the head and shortness of the body. The Heterostoma? are 

 marked instances of the very same type of species existing on the western 

 coast of Australia as on the corresponding shores of Africa.

M. Brandt expresses some doubt whether this species is not identical with 

 Scolopendra Eydouxiana of M. Gervais, which it seems to approach very 

 closely. If such be the case, it may prove to be identical with 8. (Hetero- 

 stoma) trigonopoda of Dr. Leach.

From the general character of the spines on the legs of these two species, »s 

 described by Brandt, I suspect that they may belong to this genus, but I have 

 not yet had an opportunity of examining them ; and M. Brandt's description 

 does not enable me to decide the question., as the number of joints to the an- 

 tennae is not stated, nor the form of the head indicated.
