264 APPENDIX. 



NOTE to page 106. 



Stannius, see Miiller's Archiv f. 1843, has found true Lymphatic hearts 

 in the Stork among the Grallatores, in the Ostrich and Cassowary among 

 Brevipennes, and, in the Natatores, in the Goose, Swan, Diver, and Auk. 

 He has as yet failed to detect them in the Fowl and Turkey. Panizza was 

 previously acquainted with their existence in the Goose ; these hearts lie 

 near the sacral bone, are connected with lymphatic vessels, and a vein 

 issues from them. As yet they have not been observed to pulsate, though 

 they exhibit distinct fasciculi of transversely-striated muscular fibre. 



NOTE to page 117. 



Tschudi, in Miiller's Archiv f. 1843, describes a remarkable structure 

 of the Trachea and Inferior larynx in Cephalopterus ornatus, which seems 

 to agree closely with that in the Duck ; it consists of an expansion of the 

 trachea below the superior larynx into a large elongated drum-like cavity; 

 the inferior larynx is also similarly dilated ; this structure is the more re- 

 markable from its occurring in one of the order Passerinse and family of 

 Coracinida3. The bird utters a loud and unpleasant howling cry, and 

 occurs in the same latitudes, namely, S. America, as the Howling Apes. 



NOTE to page 176. 



Bachthold, u'ber die Giftwerkzeuge der Schlangen, Tubingen, 1843, gives 

 beautiful figures of the Poison glands of Hydrophis pelamys and Naija 

 rhombeata. The length of the poison gland of the latter amounted, in a 

 specimen eighteen inches long brought from the Cape, to three inches, or 

 a sixth part of the length of the body ; it is placed parallel to the verte- 

 bral column like a broad band, and surrounded by a strongly-attached 

 muscle, which draws the gland forward or toward the head; the gland 

 consists of six perfectly parallel tubes, or long casca, two of which unite to 

 form a common excretory duct. The poison tooth is not, however, of 

 large size. 



Fischer's Amphibiorum, nudorum neurologix specimen primum, Berol, 

 1843, contains beautiful illustrations of the cerebral nerves of Bufo, Hyla, 

 Bombinator, Pelobates, Pipa, Salamandra, Triton, Proteus, and Cecilia.
