MAMMALIA. 
the Cetacea to the Pinnipeds and to Zeuglodon. Capellini (63), 
Portis (299), and Probst (303), have all described a large number 
of new species of fossil Whales, and finally, Van Beneden (39), 
Collett (71), and Aurivillius (21), have each written monographic 
essays upon recent species. 
The year 1886 has also been marked by the appearance of a consider- 
able number of new journals, containing papers on Mammals. Among 
the most important of these for the student are the “ Zoologische 
Jahrbucher, ,, edited by Spengel ; the “ Anatomisoher Anzeiger,” which 
contains papers on comparative as well as on human anatomy, and the 
“ Journal of the Bombay Natural History Society.” 
Tho number of new genera of Mammals described in 1886 is 32, as 
against 25 in 1885. Of these the majority (twenty-seven) are fossil ; of 
the remaining 5, 3 are merely new generic names for types hitherto 
known, while 2 — Dymecodon of True (381), a new genus of Moles, and 
Eliurus of Miln e-Edwards (242), a new genus of Rodents— are for newly- 
discovered forms. The number of new species described is 99, as against 
113 in 1885, and 103 in 1884. Of these, 23 are recent and 76 are fossil ; 
besides these there have been 9 forms described as subspecies.
