MOXOGRArn OF THE LABOULBEXIACE.E. 337 
IS distinctly peculiar, it should, I think, certainly be referred to the present, genus, since it con- 
forms in ever/ essential point to the t^-pe structure found throughout Die scries, find is less 
peculiarly modified in important points than very many of the renininini: species. The dimen- 
sions given by Giard arc much greater than those of the specimens uliieli 1 have examined. 
The smallest specimen among these measures 1.17 mm. in Kiiglh, wliile the lai-gcst hardly 
exceeds 2.2 mm. According to Ciard, however, specimens of uicdium size measure 3.1^2 mm., 
while larger individual.s may reach 4 mm. in lejjgth. In any case, however, the species is by far 
the largest of all the Laboulbcniacca;, as well as one of the most striking. Both this find the 
succeeding form appear to 1m' more closely related to L. longicoUis and what may be called the 
GalerU(e- group of the genus than to any other, but apart from the production of a pcrithccial 
neck the resemblance is not very close in any case.

Proc. Am. Acad. Arts and Sci. Vol. XXX, p. 471. 
Perithccium nearly straight, nlinost opnqiic, sometimes sli^^litly inflated, ifs {]{) noarly sym- 
metrical, truncate, its inner walls often having a cornigatcd appearance, Oio 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- 
tcriorly, the inner of which alone reaches any considerable size, branching 8ymj)odially in an 
antcro-postcrior 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, 150xl2yu.. Peri- 
thccium, 475-580 X 75-11^0 ./x, its neck, 75-150 x 35-65 /x. Receptacle, 300-400 /x, its greatest 
width, 75-100^. Appendages (longest), 500^, the branchlets about 225-250 x 7-8 /i- Total 
length to tip of perithccium, 1-1.1 mm. 
On Mormolycc phjllodes ITagcnb., 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. Kunhelii 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 aT)sence 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
