on A. Le.spezi small, the main axis of the receptacle consisting of only seven cells, the pcrithecia nearly 

 sessile and small in proportion. Spores 50 -60 X 4 /x. IVrithecia 1 10 150 X 15 00 //. (100 X 30 p in 

 small specimens), the stalk including basal cells, longest 220 X 17 /<. Total length to ti|> of perithecium 

 about 550 /« (200 080 /()• Receptacle 325 /< (1 10-350 p). Appendages longest 100 it.

Although the types of this species on A. Rhadamanthus, which are figured in the accompanying plare, 

 are strikingly unlike the other species, specimens occurring on A. Lespezi were found in the Paris collection 

 which, though distinctly smaller, have similar stiff upright appendages, and although it is not so well 

 developed, the perithecium has a distinct stalk. An examination is needed of a large number of these 

 cave forms, and it is barely possible that R. hypogoeus may tend to vary toward the present species. 



Rhachomyces Glyptomeri Thaxter. Plate XLV, fig. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXVII, p. 39. June, 1901. 



Receptacle slender, dirty translucent brown, the main axis consisting of about seven cells (below the 

 lower of the two pcrithecia which are present in the type): the appendages slightly divergent, large and 

 long, opaque brown, flexed inward near their hyaline, somewhat more slender extremities, and extending 

 beyond the tips of the pcrithecia. Perithecium short-stalked, strongly curved, slightly inflated, hyaline, 

 soiled with brownish, the tips well distinguished, blackish brown and obliquely truncate. Pcrithecia, 

 including basal and stalk-cells, about 185 X 44 p. Receptacle to base of lower perithecium 150 X 15 ft. 

 Appendages, longest 3G0 p. or more. 



On tip of abdomen of Glyptomerus cavicolus Mull. Carniola, Austria. Sharp Collection, No. 11-11. 



The solitary type of this species which is well defined by the shape of its pcrithecia and the character 

 of its appendages, is illustrated in the accompanying plate. This specimen is no doubt abnormal in pro- 

 ducing two pcrithecia, the axis of the normal receptacle probably not consisting of more than a dozen 

 cells at most; the distal portion in this specimen representing a proliferation such as is seen occasionally 

 in most species of the genus, which gives rise to a second perithecium. The cave-dwelling staphylinid 

 which it inhabits appears to be rare in collections. 



Rhachomyces Cayennensis Thaxter. Plate XLV, figs. 4-5. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 438. April, 1900. 



Perithecium rather small, yellowish, the anterior margin nearly straight, the posterior convex; the 

 tip clearly and abruptly differentiated, concolorous, asymmetrical, somewhat bent. Main axis of the 

 receptacle rather strongly curved, consisting of about twelve cells; the basal ones slender, deeply suffused, 

 those immediately above opaque slender, the rest rather large with central brown suffusions; the distal 

 cells paler. Appendages rather coarse, crowded, black-brown, opaque or nearly so, the tips mostly bent 

 outward, appressed below, somewhat divergent distally; six or more about the base of the perithecium 

 slightly longer than the rest, nearly equalling, sometimes slightly exceeding the perithecium in length. 

 Perithecium 120-140 X 25-30 //. Total length to tip of perithecium about 350 p. (average). Longest 

 appendages 140 p. 



On Cryptobiam sp. indet., British Museum No. 387. Cayenne. On the inferior surface of abdomen. 



This species is distinguished most readily by the form of the perithecium, straight on the inner side 

 and strongly curved on the outer to the peculiar and well differentiated tip: as well as by its short, stout, 

 curved form, and dense appendages. The small group of appendages characteristically curved outward 

 near the base which are shown at the left in figure 4, appear to be peculiar to this species, although in 

 some specimens they have been broken off.
