narrower, somewhat irregular lobes, which agrees with 

 many of the specimens in the Tuckerman herbarium. 

 From the descriptions, one would consider this to be the 

 Ricasolia subdissecta of Nylander (Ann. Sci. Nat. IV. 

 II : 214. 1859), but material under the latter name in 

 the Tuckerman herbarium does not agree. It is to be 

 noted, also, that Delise in the original description of 

 Sticta peltigera (Histoire du genre Sticta, 150. 1822) 

 says " supra lacunoso." Material corresponding to no. 

 18 was issued in Merrill's Lich. Exsic. no. 41.

 Concerning the correct name to be used for this species,

no. 26a is paler than usual and approaches 5^. Mougeo-

 Tuckerman herbarium.

(a) No. 37 is the typical form. 



(b) No. 30 is a more narrowed, and distinctly dicho- 

 tomous form, agreeing well with /. elongato-laciniata 

 Tuck, in Wright Lich. Cubae no. 60. 



(c) No. 28 differs from no. 30 only in being narrower 

 still (2 mm. wide or less) and the margins incurved so as 

 to make the lobes subtubular.
