Comparison of this arrangement with that seen in the common 
brown bat (Adelonycteris fiuscus), the noctula bat (Noctulinia noctula), 
and the false vampire ( Vampyrus spectrum) showed by the part taken 
by the rod in Balantiopteryx is the tendon of a pectoral muscle-fasci- 
cle which is inserted into the occipito-pollical muscle as it crosses the 
shoulder, while in the group of the Molossi the muscle-fascicle is fleshy 
throughout its entire extent, but on the whole preserving the same 
relations, Thus the fibro-cartilage of Balantiopteryx is. represented 
by fibrous tissue in Adelonycteris and both these in turn by muscle in 
the Molossi. Dr. Allen believed that it was inexact to speak of a 
clavicle and of this rod as things which were equal. The clavicle acts 
with the scapula in supporting the head of the humerus but in no wise 
limiting or determining its movements, while the rod is always over 
the outer aspect of the shaft of the humerus below its head and acts 
as a check to abduction of this bone—Proceeds. Phila. Acad., Pt. 2,

A New Synaptomys from New Jersey.—While trapping 
for a type series of the new race of Evotomys described by Mr. Stone 
in the present number of Tor Naturatist, I had the fortune to 
secure a specimen of this long-looked-for genus, which is, I believe, 
the first taken in flesh east of the Alleghany Mountains. 
It had previously been detected by the U. S. Department of Agricul- 
ture in the rejects of a barn-owl living in the tower of the Smithsonian 
Institution. 
_ A comparison of the New Jersey specimen with two Synaptomys 
cooperii from Ohio, courteously loaned by Mr. J. A. Allen, of the 
American Museum of Natural History, N. Y., shows such marked 
specific differences that it will be unnecessary to more than briefly 
allude to them. 
SYNAPTOMYS. STONEI.—Sp. nov. Type No. 567. ad. 9. coll. S. N. 
Rhoads, May’s Landing, N. J. Dec. 2, 1892. 
Special Characters—Outward appearance and proportions as in 
S. cooperti. Above blackish-brown, with black hairs more predomi- 
nant over the shorter brown hairs than in cooperii. The same color 
reaching around sides of belly instead of being confined to dorsal area 
as in cooperit. Hoary gray belly and neck of cooperii replaced by dark 
plumbeous gray. Feet, including soles, plumbeous, without brown 
shade. Two middle toes of fore-feet and four inner toes of hind feet, 
including nails, white. Tail unicolor plumbeous gray. Lips encircled 
with narrow white edgings.
