1204 The American Naturalist. [December, 
Skull of Sharks.—P. J. White has an account of the skull and 
visceral skeleton of the Greenland shark (Lemargus microcephalus) in 
the Anatomischer Anzeiger, V., No. 9. The cartilage is soft, and, 
except in the visceral arches, is without calcareous deposits. Among 
the peculiarities are the following: The neural arch of the first vertebra 
freely enters the foramen magnum ; a canal (hypophysis canal?) runs 
through the cranial floor, opening near the foot of the pituitary fossa ; 
a median cartilage intervenes between the extremities of the mandi- 
bular rami; there are other cartilages which may represent hypohyal 
elements ; the first basibranchial is present, —it had only been known in 
Cestracion of the Elasmobranchs. 
Dr. Leonard Stejneger on Bufo lentiginosus woodhousei. 
—In Animal Life, No. 3, p. 116, 189o, Dr. Stejneger, who is in 
charge of the department of reptiles in the Smithsonian Institution, 
writes as follows : ** Prof. Cope, in his elaborate work on the * Batrachia 
of North America,’ as a reason for leaving Hallowell's B. dorsalis out 
of the synonymy, makes the following statement: * There is nothing 
in the description nor the figure to enable us to ascertain what species 
or subspecies is represented. "The evidence is as much in favor of the 
specimen having been a B. Z americanus as a B. 1. woodhousei, and no 
locality is given to assist in reaching a conclusion.’ This not so, for 
in the first place Hallowell gives the locality of the only specimen ex- 
pressly as ‘San Francisco Mountain, New Mexico’ (Z.e., Arizona), 
and the second place mention is made of the shortness of the head 
(* Length of head, 8 lines ; length of head and body, 3 inches,’ con- 
sequently ‘ head 4.5 times in length’). Moreover, Girard, who after- 
wards examined and partly described the type specimen, simply 
changed the name because 2. dorsalis was already preoccupied by 
Spix, and we are well warranted in regarding the only specimen brought 
home by Dr. Woodhouse as the type of B. woodhousei. Finally, the 
type of B. dorsalis, so far from not being found, is one of the very 
specimens enumerated by Prof. Cope, viz., No. 2531. The ‘ Calit 
Mountains’ in the original entry on the museum record book is simply 
aslip for San Francisco Mountain, and is evidenced by. the original 
parchment label still attached to the specimen, which reads: ‘Bufo 
dorsalis, Hallowell, San Francisco Mountain, New Mexico; S. W. 
Woodhouse, M.D.’ This also disposes of another statement by the 
same author, that Möllhausen’s specimen from the Canadian River 
(U. S. Nat. Mus., No. 2632) is the type. Girard at the time of pub- 
lishing the name Z. woodhousei had only the * Sonoran’ specimens from
