If, the species is, 



2. the internal are close together, and the external are only 



slightly branched, (as in Plate II, figure 1,), umbrosus* 



3. the internal are of one of the types represented in Plate II, 



figures 2 & 2A, while the external are pronged aitkeni. 



4. the anterior hairs are strongly frayed, and the posterior 



branched, (Plate II, figure 3,), albirostris.^ 



* There are no palmate hairs. 



-( Sometimes the anterior hairs of albirostris are less frayed, and as those of maculatus and karwari may 

 be sometimes more than usually frayed, (see Plate III, figures 1 & 2), there may be a chance of confusing the 

 first with the last two, but the branched posterior hair of albirostris settles the point, or if that is not seen, a 

 reference to the palmate hairs, (compare Plate VI. figure 4, with Plate III, figures 1A & 2A.).
