720 THAXTER 



what more than a quarter of a turn, indicated by fine, more or less 

 distinct dark lines of separation; the body somewhat inflated, taper- 

 ing distally to the broad, slightly angular, or oblique termination; 

 the rather coarse lip-edges hyaline, or olivaceous, irregularly promi- 

 nent; the anterior lip-cell developing a slightly curved, blunt-tipped, 

 erect free projection of nearly uniform diameter; which, owing to the 

 twisted wall-cells, appears to be lateral (left). Spores approximately 

 25 X 3 ;u (measured in perithecium) . Perithecium 85 X 22 /x ; its 

 terminal projection 10-12 X 3.5— i jjl. Receptacle to insertion-cell, 

 120 /i; basal and subbasal cells 62 X 12 m; cell III-IV 35 X 16 /x. 

 Appendage about 225 /x. Total length to tip of apical projection 

 about 175 /J,. 



On the abdomen of Hippelates sp., No. 2516, Bocas del Toro, 

 Panama. 



I am indebted for the host on which this very distinct and graceful 

 species was found, to the kindness of Mrs. J. B. Rorer. Only four 

 specimens have been examined, in which antheridia are no longer 

 present, or are not visible on the partly concealed appendage. The 

 insertion-cell is similar in all respects to that of normal types; but, 

 as in the two preceding species, the receptacle is of the ' Laboul- 

 beniella type ', cells III and IV being replaced by a single cell. 



Laboulbenia anguifera nov. sp. 



Long and slender, straight, or more or less curved; the subhyaline 

 basal and subbasal cells contrasting abruptly with the uniformly 

 dark olive brown portions above. Basal cell nearly uniform through- 

 out, one third to one fourth as long as the subbasal cell; which is 

 broader and nearly uniform, except for an abrupt, bulb-like, subsym- 

 metrical enlargement at its base, which may be twice the diameter 

 of the basal cell; somewhat obliquely separated from cell VI; which 

 is relatively small, as well as from the relatively small cell which 

 corresponds to cells III-V, and is externally thick-walled and slightly 

 convex. Insertion-cell broad thick and opaque, the minute hyaline 

 basal cell of the inner appendage obliquely separated from it, and 

 bearing a branch on either side, distinguished by a blackened septum, 

 and producing single, straight antheridia with hardly differentiated 

 necks; as well as two to four erect, slender, tapering, faintly brownish 

 simple branchlets, which may reach as far as the apex of the perithe- 

 cium : basal cell of the outer appendage blackened externally and dis-
