132 FISHES OF SAN DIEGO—EIGENMANN. 
GENERAL REMARKS ON THE INDIVIDUAL SPECIES. 
I have endeavored to collate references to San Diego fishes. . 
BRANCHIOSTOMID®. 
Branchiostoma elongatum Sundevall. 3 
81. 29 (not seen). As B.lanceolatum. Gill, Proc. U. 8. Nat. Mus., v. 1882, 
515; Rosa Smith, July, ’85, 55. E. Am. Nat. 1892, 70. 
Before 1891 three specimens of this species were known from San Diego 
Bay. They were taken by Dr. Cooper in 10 fathoms of water near Rose- 
ville. During July, 1891, I took a large number near Ballast Point, 
where a dredge was deepening the channel.

HETERODONTID&. 
Heterodontus francisci (Girard). 
Jordan & Gilbert, ’80, 34; Rosa Smith, July, ’80a., 458., id., 82,30. R. Smith, ’85. 
This species is very abundant at San Diego both in the bay and out- 
side. The eggs are often driven ashore and lodged between rocks in 
tide pools or are thrown on the beach. Several eggs ready to hatch 
have in previous years been found during January. <A female about 1 
meter long opened March 27, 1889, by some fishermen, contained anegg | 
inclosed in its twisted shell. 
SPINACID2. 
Squalus acanthias Linneus. 
E. & E., ’89,1; ’89a, 12. | 
This species is very abundant at the Cortes Banks. One specimen, 
taken in July was with young, 22 millimeters long. One individual 
caught a short distance off Point Loma, January 9, 1890, was with 
young, 11 millimeters long. In these the external gills had already 
disappeared and the characteristic color of the adult was developed. 
It has not been seen in the bay. 
SCYLLIDZ. 
Scylliorhinus ventriosus Garman. 
Rosa Smith, ’85. E. & E., ’89, 13. 
We have not seen the adult of this species at San Diego. The empty 
dried egg cases are frequently thrown up on the beach and occasionally 
live ones are found. They are extruded during December (February 
at Santa Barbara, J. & G.). The young have been described by us 1. ¢ 
It has not been taken in the bay.
