the lachrymal process, is a foramen — the outer precranial foramen 

 {ope) — separated by a ridge from the fossa before described ' as 

 bounded postaxially by the crucial ridge, and beneath it the crucial 

 ridge {cr) is plainly to be seen passing outwards from the cranial 

 septum to the adjacent surface of the lachrymal. At the bottom 

 of this fossa is {ipc) the inner precranial foramen. 



External to the distal end of the lachrymal on either side is the 

 postorbital process (po), beneath which is the notch interposed 

 between it and the sphenotic process {sph). Passing inwards 

 from the postorbital process to the vicinity of the optic foramen 

 (opf), the transverse ridge before noticed ^ {tr) is to be seen. 

 Finally between the paroccipital processes is the basi-temporal 

 shield {hts), beneath the middle of which is the prominence of the 

 occipital condyles {oc).

Anterior aspect (prosopium being removed) of Lorivs flavopalliaius. 

 (Lettering the same as in fig. 9.) 



In Lorius flavopalliaius, thus seen, the transverse groove is 

 shorter, the lachrymal is notably longer, and the paroccipital pro- 

 cesses ai'e narrower, less blunt and rounded distally, and more 

 inclined mesiad ; the basi-temporal shield is also relatively as well 

 as actually narrower from side to side. 



The postbrioe. aspect of the cranium presents, in P. erithacus, 

 a dorsal margin which is very convex on either side but slightly 

 concave in its middle. Laterally its outline is mainly straight and 

 vertical with certain projections : these are, above, the postorbital 

 margin ending in the postorbital process, beneath which is a small 

 sharply marked concavity limited below by the projection of the 

 suprameatal process. Just below this, again, is another con- 

 cavity (as sharp as, though shorter than, the preceding one) which
