96 THE NAUTILUS. 



Quirigua (W. P. Cockerell, 1912). Nicaragua: Chontales 

 forest, in moss on trees (Tate, type of H. c&coides). Rep. de 

 Panama: Boco del Toro (Tate, in A. N. S. P.); City of Panama 

 (James Zetek). 



This species differs very little from 2'. 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 T. ccecoides is in the collection of the 

 Academy, No. 12159, 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 Strebel (1880) be- 

 longs to this species, but the photographic figure shows only a 

 very small umbilicus as in csecoides. 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 Pica 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 small 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;
