LICHENS OF ' CHLORIS MELYILLIANA.' 115 



upon L. elegans, in 'Prodr.,' p. 102 — "as if intermediate between 

 L. murorum and L. parieti7iiis." In one of the other two specimens 

 the apothecia are crowded, with the margins in most cases beauti- 

 fully crenulated (f. crenata, Cromb.) 



No. 102, s. n. Borrera ? aurantiaca, E. Br., s]3. n. = Phi/scia 

 nodulifera, Nyl. — Sterile. Although the locality on the accom- 

 panying label is Winter Harbour, yet, having regard to the 

 distribution of this sj)ecies, I cannot but think that the specimen 

 got accidentally mixed up with the Lichens of Melville Island, and 

 that it really belongs to Gardner's Brazil Lichens, which I found in 

 close proximity. 



No. 103, s. n. Cetra7-ia juniperina , Ach. = Platysmajuniperinum, 

 (L.) — Stunted and sterile, with the laciniae much congested. 



No. 104, s. n. Cetraria nivalis. = Platijsma nivale (L. ) — Sterile. 

 No. 105, s. n. Cetraria cucuUata = Platijsma ciicullatum (Bell). 

 — Sparingly fertile. Along with the type are also two fragments 

 of f. tapeina, Ach., — a stunted and broader state of the plant. 



No. 106, s. n. Cetraria islandica. — Here are two specimens, of 

 which a. = Cetraria Delisei, Schser., sterile ; and h = y?li\ fastigiata 

 (Del.), Nyl., sparingly fertile. 



No. 107, s. n. Cetraria odontella, Ach. = Cetraria Delisei, var. 

 suhmedia, Nyl., in ' Norrl. Lapp.,' p. 323. — Sterile. 



No. 108, s. n. Peltidea aphtliosa ^ Peltidea aphthosa (L.) — A 

 small sterile specimen. 



No. 109, s. n. Cornicularia ochroleuca = Alectoria ochroleuca, 

 (Ehrh.) — Sterile specimens with the thallus less robust than we 

 have seen from other Arctic regions. 



No. 110, s. n. Cornicularia lanata = Alectoria divergens, Ach. — 

 Sterile. 



No. Ill, s. n. Cerania vermicularis = ThamnoUa vermicularis, 

 (Sw.) — Sterile. A form with the stipites more robust (turgid), 

 shorter, often deformed, and less cornuted than in the type 

 (f. Melvilliana, Cromb.), but probably not constant. The sup- 

 posed apothecia described by R. Brown in the specimen gathered 

 by Dr. Fischer are not anything rightly evolute, the black spots 

 being caused by the presence apparently of some minute alga. 



No. 112, s. n. Cenomyce pyxidata = Cladonia ijyxidata, L. — 

 Fragmentary and sterile. 



No. 113, s. n. Stereocaulon paschale = Stereocaulo7i tome7itosu7n, 

 Laur. — Sterile. 



No. 114, s. n. Usnea sphacelata, E. Br. = Neuropogon melax- 

 anthits, f. sphacelata, sorediiferous. — Sterile, as the plant always is 

 in Arctic regions. 



In addition to these there occur in the herbarium from Melville 

 Island the two following species not enumerated by him in the 

 ' Chloris ' :— 



1. Dactylina arctica (Hook.) — A fragmentary infertile specimen. 



2. Parmelia centrifuga (L.) — Sterile. 



Arranged in order the above Lichens will, therefore, stand as 

 follows : —
