even larger, externally somewhat convex, the rest successively some- 

 what smaller and externally abruptly convex, somewhat obliquely 

 superposed ; two or three of the terminal ones slightly proliferous, the 

 rest bearing appressed antheridia, usually turned inward. Primary 

 stalk-cell of the perithecium somewhat exceeded above and below by 

 that of the appendage; secondary stalk-cell subtriangular, placed 

 somewhat higher, and obliquely separated; the basal cells about as 

 large, the outer often abruptly convex externally: venter asymmetri- 

 cal, distally broader; the wall-cells with a distinct spiral twist, distally 

 cushion-like, and forming broad prominences, the outer lower: the 

 distal portion of the perithecium undifferentiated, stout, of nearly 

 uniform diameter throughout, the broad bluntly rounded apex bent 

 outward. Spores about 18 X 2.5 m- Perithecia 100-105 X 28-32 ^ 

 (venter) X 14 /i (distal portion). Appendage about 40-50 /i. Recep- 

 tacle 40-50 /x. Total length to tip of perithecium 150-175 ;u. 



On tip of abdomen of Limosina sp. No. 2739, Kamerun, W. Africa. 



A species somewhat similar to S. affinis in the conformation of its 

 venter, but differing in its longer basal cell region, and stout uniform 

 distal portion, ending in a curved bluntly rounded broad apex. 



Stigmatomyces Limosinoides nov. sp. 



Nearly hyaline or yellowish, with a slight general sigmoid curvature, 

 the perithecium tinged with yellowish brown. Receptacle rather 

 long, curved below, the convexity anterior; the basal cell tapering 

 slightly to the faintly suffused yellowish base; the subbasal cell longer 

 stouter, distally more or less distinctly inflated below the two parallel 

 vertically elongated stalk-cells, the combined bases of which are some- 

 what narrower. Stalk-cell of the appenjlage more than twice as 

 long as broad, slightly longer than that of the perithecium, rather 

 prominently rounded below the insertion, which lies slightly higher 

 than the end of the perithecial stalk-cell: the axis of the appendage 

 tapering, consisting of six to eight cells, the basal small, short, clear 

 amber-brown, the rest rounded, somewhat flattened, strongly convex 

 externally, successively smaller, all but the two or three terminal ones 

 bearing appressed antheridia, the lower superposed in pairs ; the upper- 

 most cells small and sterile. Secondary stalk-cell about twice as long 

 as broad, similar to the primary, but slightly shorter, lying wholly 

 above it, its base and that of the inner basal cell coincident and slightly 

 oblique: basal cells relatively large, surrounding the rather long nar-
