XIX -THE OSTEOLOGY OF AMIA CALVA: INCLUDING CER- 

 TAIN SPECIAL REFERENCES TO THE SKELETON OF TELEOS- 



TEANS.

The present paper will be divided into two parts ; of these, Part I will 

 consist of a translation of the admirable article of Dr. M. Sagemehl, 

 entitled ^'- Beitrdge zur vergleiclienden Anatomie der Fisehe,'''' the first con- 

 tribution given ns being "I. Das Crmiium von Amia calva, L," This 

 carefully written essay appeared in the second part of the ninth volume 

 of the Mo7-phologisches Jahrbuch, for the year 1883. It is illustrated 

 with one double-page, beautifully executed plate. The twelve figures 

 in this plate I have had, through the kindness of Professor Baird, care- 

 fully copied by Mr. H. L. Todd, the artist of the Fish Commission and 

 Smithsonian Institution. They appear in their proper places in the 

 plates illustrating this article with their explanations set opposite to 

 them. 



In Part II it is my intention to review the conclusions arrived at by 

 Bridge, after his study of the skeleton of this interesting form. This 

 anatomist published his well known memoir in the Journal of Anatomy 

 and Physiology (Vol. XI, 1877, pp. G05-622, Plate XXIII), six years 

 before Dr. Sagemehl's results appeared in the Jahrhucli. In this part, 

 too, I will bestow a passing glance upon the monograph of Henricus 

 •Franque/ and compare his figures with those given by the above 

 authors. Beyond this, however, it is not my intention to pass further 

 into the literature of the subject, as the short and unsatisfactory 

 accounts given by the older writers would avail us nothing here. 

 Finally, I propose to present a few observations of my own, which have 

 been the result of an examination of a skeleton of Amia^ carefully 

 prepared from a specimen of this fish which I captured in the vicinity 

 of Xew Orleans, La., during the summer of 1883. This preparation was 

 done for me in the most skillful manner by Mr. J. L. Wortman, the 

 anatomist of the Army Medical Museum, of Washington. A few figures 

 will be presented in this part, illustrating points that do not appear in 

 Dr. Sagemehl's article.
