CHITONOMYCES AND RKKIA. 7 



what resembling the human ear in outUne, convex below, its axis 

 horizontal, bearing the foot on its flat upper margin, near one end of 

 which the short distal portion of the cell, narrow below and abruptly 

 broader above, arises; cell h small, flattened, horizontal, somewhat 

 irregular, producing a more or less well dexcloped outgrowth from its 

 anterior margin, which may project outward horizontally or grow 

 downward against the termination of the basal cell, from which it 

 may appear to arise; cells c, d and e small, flattened, irregular and 

 confuses! with one of the persistent basal cells of the perithecium; 

 cell (' smaller, subtriangular, separated from cell h by the whole width 

 of cell d; marginal region evenly convex; cell /long, narrowing below 

 to its oblique base, distally somewhat overlapped by cell g, which is 

 larger than cell h; cell i longer than broad, tapering to its rounded 

 extremity, strongly curved inward so as slightly to overlap the tip of 

 the perithecium, thus making the primary appendage horizontal in 

 position. Perithecium relatively large and stout; the outer margin 

 nearly straight; a variably developed rounded elevation projecting 

 externally near its base; the short abruptly distinguished tip bent to 

 the right, then outward; subtended externally by a variably devel- 

 oped erect outgrowth, which tapers to a blunt point and may exceed 

 the somewhat irregular apex, which is slightly compressed about the 

 pore; a long, straight, curved or subsigmoid, more deeply colored, 

 divergent, then erect appendage, tapering from a broad base to a 

 sharply pointed or somewhat blunt, attenuated apex, arises from one 

 of the wall-cells close beside the end of cell h on the right side, and 

 extends some distance above the apex of the perithecium. Spores 

 about 40 X 4 /i. Perithecia 72 X 30 m; the outer spine 21-26 /jl, the 

 inner 45-55 /x; inflated part of basal cell 36 X 23 /x. Total length to 

 tip of perithecium 100-120 X 35 /x. 



Growing singly between the terminal claws of the posterior legs of 

 Laccophilus sp.; Sangre Grande, Trinidad, B. W. I., No. 2684, and 

 the Grand Etang, Grenada, No. 2687. 



A very peculiar species, at once distinguished by its swollen base, 

 which is evidently an adjustment to its peculiar habitat, and by its 

 perithecial appendages. 



Chitonomyces Grenadae nov. sp. 



Tinged with dirty brownish, rather irregularly developed. Basal 

 cell longer than broad; cell b somewhat flattened, horizontal, more or 

 less clearly distinguished above and below by constrictions; cells c, d
