96 THE NAUTILUS. 
Quirigua (W. P. UCockerell, 1912). Nicaragua: Chontales 
forest, in moss on trees (Tate, type of H. cxcoides). Rep. de 
Panama: Boco del Toro (Tate, in A. N.S. P.); City of Panama 
(James Zetek ). 
This species differs very little from TJ. plagioptycha or fuscula 
in size, general shape and sculpture, but is readily distinguished 
by the very small, partly covered umbilical perforation. The 
umbilicus, while small, is much larger in the other species. 
Part of the type lot of 7. cecoides is in the collection of the 
Academy, No. 12155, received from Prof. Tate. The original 
figures of H. guatemalensis are hardly recognizable, but those in 
the Mexican monograph are fairly good. I am not quite sure 
that the East Mexican Acanthinula granum Strel 21 (1880) be- 
longs to this species, but the photographic figure shows only a 
very small umbilicus as in cecoides. This may be taken up 
when topotypes are available. 
The locality records are all for specimens in the collection of 
the Academy. Specimens from Costa Rica are still wanting. 
LAND SHELLS OF MAINE. 
BY E. G. VANATTA. 
While botanizing in Maine in 1916 Mr. Bayard Long col- 
lected leaf mould containing land shells at numerous localities. 
A list of these stations with brief statement of the conditions 
and the dates is given below, the locality being condensed to a 
single word in the following list of species. 
While most of the species have been known from Maine, it is 
hoped that the list will have interest to those who may study 
the details of distribution in the State. 
York Co.—In moist woods bordering the salt marsh at 
Kittery, viii, 11; in moist woods at York, viii, 9; at the edge of 
a spring rill on the border of the salt marsh at Wells, viii, 8; in 
moist thickets along a smal] stream at Limington, viii, 29. 
Cumberland Co.—In a moist wooded gulley near Steep Falls 
in Baldwin, viii, 28; around Sand Pond, Baldwin, viii, 30;
