tions a bat (9, no. 12588, Mus. Vert. Zool.) taken at Errington, 
August 31, 1910, which he refers to the form Myotis lucifugus 
alascensis, stating that ‘‘the specimen is so imperfect as not to admit 
of exact identification.’’ While the tibiae of this bat are mutilated, 
it is otherwise in good condition and the skull is perfect, showing the 
up-turned rostrum and the facial angle typical of Myotis longicrus 
longicrus. The forearm of this bat measures 36 millimeters, the 
greatest length of cranium, 14.3, and breadth of brain-case, 7.5. In 
color this example is very close to the specimen from Admiralty 
Island, Alaska, described above, but the hair tippings both above and 
below are lighter, more ochraeous-buff. 
In so far as the writer is aware Myotis longicrus longicrus has not 
hitherto been recorded from farther north than the type locality, 
Puget Sound, Washington. 
Myotis lucifugus alascensis Miller 
Among some bats belonging to the Biological Survey collection, 
United States National Museum, and loaned to the writer through the 
courtesy of Mr. E. W. Nelson, are four skins (three with skulls) from 
Skidegate, Queen Charlotte Islands, British Columbia. These speci- 
mens (nos. 100675-100678) are adult males collected by W. H. Osgood 
in July, 1900, and are presumably the four recorded (Osgood, 1901, 
pp. 36, 37) under the name Myotis ywmanensis saturatus. The three 
skulls measure in millimeters: no. 100675, greatest length of cranium, 
14.7; breadth of brain-case, 7.3; no. 100676, greatest length of cranium, 
14.7; breadth of brain-case, 7.6; no. 100677, greatest length of cranium, 
14.9; breadth of brain-case, 7.4. The specimens in all their characters 
show their identity with the bat now currently known as Myotis 
lucifugus alascensis. 
Myotis californicus caurinus Miller 
There are in the collection of the Museum of Vertebrate Zoology 
two mummified specimens of Myotis californicus caurinus collected by 
W. D. McLeod at Howkan, Long Island (near Dall Island), south- 
eastern Alaska. These bats measure in millimeters: no. 19292 (skull 
removed) : forearm, 31.7; tibia, 12.3; thumb, 3.6; greatest length of 
skull, 13.1; breadth of brain-case, 6.8. No. 19293: forearm, 32.2; 
tibia, 13.5; thumb, 3.9. In color these two examples are closely
