Four lists of the fishes of San Diego have been published. Jordan 
and Gilbert in their first list, referred to as J. and G.,’80 (Proce. U.S. Nat. 
Mus., 1880, 23) gave notes on fifty-seven species collected by them. Rosa 
Smith, in her first list, referred to as R. Smith, ’80 (Nov., 1880), enume- 
rated cighty-two species. In their second list Jordan and Gilbert, ’80a 
(J. c. 452) enumerated eighty three. The fourth, or Rosa Smith’s second 
list, 85 (West American Scientist, June, July, and August, 1885), con- 
tained the names of one hundred and nine species. 
In the Proceedings of the U.S. National Museum for 1881, Jordan 
and Gilbert give notes on the fishes of the Pacific Coast in general. 
This paper is quoted as J.and G.,’S1 ; their synopsis of the fishes of North 
America as J. and G.,’82. Our three papers, Notes from the San Diego 
Biological Laboratory, 1, 11, and 11, are referred to as 789, 89a, and 790, 
The other papers are quoted in full. 
The present list enumerates one hundred and seventy species and 
varieties. Of these I have observed all but the following during my 
stay at San Diego. (1) Carcharinus lamiella; (2) Manta birostris; (3) 
Hippocampus ingens; (4) Siphostoma punctipinne; (5) S. Californiense; 
(6) Gasterosteus microcephalus; (7) Caranx caballus; (8) Chetodipterus 
Jaber; (9) Neoclinus blanchardi; (10) Spheroides politus; (11) Diodon 
hystrix. 1 am not certain whether numbers 3, 7, 8,10, and 11 of the 
foregoing should not be discarded. They have not been taken here 
within the last ten years. The others have been taken either by Rosa 
Smith prior to 1887 or they have been authoritatively recorded from 
here by others. The species (60) added to the San Diego fauna during 
the period covered by this paper have already been enumerated: in 
the Proceedings of the U. 8S. National Museum, 1888, 463: the West 
American Scientist for October and November, 1889: the Proceedings 
of the California Academy of Sciences, second series., vol. 111, p. 1, 1890, 
and in the American Naturalist February, June, and December, 1891, 
and January 92. Of the sixty species added over twenty were new to 
Science, most of the others being forms already well known from the 
northern part of California. Comparatively few southern species have 
been added. 
_ I have found surprisingly few species of pelagic fish eggs. This is 
probably due to the limited means of collecting them and to the fact 
that at least 30 per cent of the teleosts inhabiting the region are vivip- 
. arous. 
_ The following synoptical key will perhaps assist future investigators 
to identify some of the species of fish eggs found at San Diego.
