arranged in radii from a central point.» G. C. W., 1. c. Whether this be correct or 

 not, the specimen from which I figured f. 35 had remnants of endochrome shewing t/r<> 

 pyreno*i'ds in each semicell, as depicted. Wallich states that the ends are somevvhat 

 rounded, in my speeimens one had straight, the others slightly incurved, apices. The 

 frond is smooth.

 visum est.

The markings on this form are verv peculiar, being so black in colour; those on 

 certain XanthicHa are frequently bluish-black or dark purple by transmitted light, bu1 

 these are much darker.

This species seems to be very polymorphic as to its surface, its outline being 

 fairly regular or constant. Nearest to ( '. granatum Breb. (in Ralfs 1 Br. Desm. p. 96, 

 t. XXXII, f. 6) and C. pseudo-granatum Nordst. (Desm. Brås. p. 211, t. III, f. 27).
