is distinctly peculiar, it should, I think, certainly be referred to the present genus, since it con- 

 forms in every essential point to the type structure found throughout the scries, and is less 

 peculiarly modified in important points than very many of the remaining species. The dimen- 

 sions given by Giard arc much greater than those of the specimens which I have examined. 

 The smallest specimen among these measures 1.17 mm. in lengtb, while the largest hardly 

 exceeds 2.2 mm. According to Giard, however, specimens of medium size measure 3.132 mm., 

 while larger individuals may reach 4 mm. in length. In any case, however, the species is by far 

 the largest of all the Laboulbcniaceae, as well as one of the most striking. Both this and the 

 succeeding form appear to be more closely related to L. longicollis and what may be called the 

 Galeritce group of the genus than to any other, but apart from the production of a perithecial 

 neck the resemblance is not very close in any case.

Pcrithecium nearly straight, almost opaque, sometimes slightly inflated, its tip nearly sym- 

 metrical, truncate, its inner walls often having a corrugated appearance, the four lower wall- 

 cells elongated and contracted to form a short stalk below and about one third as long as the 

 ascigerous portion. Appendages rigid and but slightly divergent, arising from two small basal 

 cells : an outer which gives rise to a series of two or three opaque branches placed antero-pos- 

 teriorly, the inner of which alone reaches any considerable size, branching sympodially in an 

 antero-posterior plane, the main axis opaque, successively inflated below the branchlets, which 

 are usually about ten in number, opaque with hyaline tips ; an inner which gives rise to a single 

 branch on either side, consisting of a sub-cylindrical basal cell, black below, nearly hyaline 

 above and followed by a series of sympodial branchlets like those of the outer appendage. 

 Receptacle short, tapering rapidly to the base, wholly black and opaque with the exception of the 

 whole or a portion of its basal cell, which may be hyaline, and is abruptly bent above the very 

 large hoof-like haustorium or blackened point of attachment. Spores, 150x12^. Peri- 

 thecium, 475-580 x 75-110 fi, its neck, 75-150 x 35-65 fi. Receptacle, 300-400 fi, its greatest 

 width, 75-100 Appendages (longest), 500 /z, the branchlets about 225-250 x 7-8 fi. Total 

 length to tip of perithecium, 1-1.1 mm. 



On Mormolyce phyllodes Hagenb., Perak, Molucca, Java. 



The writer is indebted to the late Professor Riley for abundant material of this species 

 found by Mr. Schwarz on a specimen of Mormolyce in the National Museum labelled "Java," 

 as well as to Mr. Beutenmueller, who has kindly sent material derived from a specimen in the 

 Central Park Museum labelled Molucca, and to Professor Giard, who has also generously 

 allowed him to examine the original specimen of Mormolyce from Perak, on which the types of 

 L. Kunkelii were associated with the present species. The two species are very closely allied, 

 and were found intermingled toward the base of the elytra, although the smaller was much 

 more abundant on the flattened margins, where it presents the appearance under a hand lens 

 of a grove of little palm-trees. The absence of any transitional forms between the two species 

 seems to render it unlikely that they should prove merely varieties of a single form, while the
