"A most valuable and complete history of these animals, especially of those found in North America, of their distribution and pursuit,

Preliminary List of Works and Papers relating to the Mammalian Orders Cete and Sirenia.<BuH. U. S. Geol. 

 and Geogr. Surv., VI, No. 3, pp. 399-562, Aug. 30, 1882. 



Covers the period from Albertus Magnus (1495) to the year 1840, and numbers 1013 annotated titles, the annotations in many cases 

 amounting to a full statement of contents, so far as pertinent to the present subject, including names of species and genera and nature 

 of treatment. All thus far published. The cause of the discontinuance of publication is explained in an insert, as follows: 



11 Owing to the illness of the author, which prevented his revision of the proof-sheets, it was necessary to stop the printing of the ' List' 

 at the end of the year 1840. The present instalment comprises only a little more than one-third of the article; the remainder will be pub- 

 lished as soon as the author's health renders it practicable. — J. A. Allen, Cambridge, Sept., 1882."
