1. I*i:*iistiims crucifer, Val. 



Numerous specimens. Obbia and route from Obbia to Berbera. 



The largest measures 35 millim. from snout to vent. The tail 

 is very slightly compressed, not at all keeled. This lizard holds, 

 in fact, an intermediate position between Pristurus and Agamiira. 

 The nostril is pierced between two, three, or four nasals ; the 

 upper labials vary in number from four to six, and there are 

 four or five lower labials. Some specimens have a light verte- 

 bral stripe , others not ; the sides are often ornamented with 

 small bright orange or brick-red spots or interrupted lines. 



P. crucifer is known from Abyssinia ( Valenciennes)^ Somaliland 

 (Révoil^ Rohecchi), Assab (Doria) and Aden {Boria). 



2. Hem.i<iactyliis iia.a.lbiLÌa., Mob. 



A single specimen. Obbia. 



3. Ijyg:od.aetylixs pictxiratxis, Peters. 



A single specimen, without tail. Route from Obbia to Berbera. 



Although a male, the specimen shows no trace of black colour 

 on the throat; it has only six praeanal pores. In other respects, 

 it agrees well enough with L. picturatus, of which specimens 

 from Somaliland, received from the Paris Museum, are preserved 

 in the British Museum.

 four between the orbits ; occipital not enlarged ; no spines on
