10 THAXTER. 



On the inferior surface of the abdomen near the tip and on the 

 forceps of Labia pilicornis Motsch. Peradenyia, Ceylon, No. 2112. 



This species is allied to D. Labiae and D. rninutii'tsimus from both 

 of which it is distinguished by its pedicillate perithecium, as well as 

 by other points of difference. The specimens obtained from the 

 al)domen differ distinctly from those which grow on the forceps, the 

 secondary appendage of the latter lying parallel to the receptacle and 

 primary appendage, instead of projecting at right angles as in the 

 material from the abdomen, in which this appendage is also longer, 

 darker and more conspicuous. The two seem otherwise practically 

 identical. 



Rickia rostrata nov. sp. 



Axis hyaline indeterminate broad, somewhat narrow below, elongate, 

 its margins somewhat uneven, the cells relatively large and thin-walled. 

 Foot small, basal cell of the receptacle broader than long, the sul)l)asal 

 cell flattened, slightly intruded between two small nearly equal cells 

 which lie right and left above it and form the bases of the two lateral 

 rows of the axis which consist of three cell-rows: the cells of the axial 

 row somewhat larger than the others, seldom o\er twenty in number, 

 rarely twenty-seven but often less, the lower more or less elongated 

 vertically, those below the perithecium often shorter, the distal por- 

 tion of about six small cells ending below the base of the primary 

 appendage and in contact with the venter of the perithecium, the 

 wall-cells of which become obliterated in this region: the cells of the 

 anterior and posterior rows similar, narrower, a majority of them 

 appendiculate, the anterior row of seldom more than twenty cells, often 

 less, rarely twenty-five : the posterior row of twenty-two cells or less, 

 rarely thirty, ending at the base of the rostrate tip of the perithecium, 

 where it bears the primary appendage. Primary appendage smaller 

 than the secondary ones, short, hyaline, evanescent ; the base relatively 

 small, truncate-conical, projecting free at an angle of 45° or less to 

 the axis, distally suffused. Secondary appendages hyaline, variably 

 elongate, mostly evanescent, subtended by a small cell separated from 

 the axis-cell which is prolonged to form a slender dark purplish brown 

 base simulating an appendage, free and projecting horizontally out- 

 ward, or more often obliquely upward. Antheridia similarly borne, 

 their irregular cells becoming more or less free in a mucus group. 

 Venter of the perithecium hyaline, or faintly tinged with yellowish 

 brown, broad, rounded outward, the ascogenic cell placed laterally
