return of tide during summer. Towards their spawning season 
they retire to their respective crab holes, and no morsel, be it ever 
so tempting, will lure them forth. They first spawn at San Diego 
about the end of March. The young, when first observed, have 
but a few color cells. They are very active, jumping several times 
their own length, if left dry in a watch crystal. Under the micro- 
scope a series of slender threads are seen to extend out from the 
lateral line (figs. 18 and 19), and similar threads are grouped about 
the head. Provided with such delicate tactile organs and well-de- 
veloped eyes, the young Gillichthys is well equipped for its early 
existence. 
As hinted above the young, not larve, of this species but little 
resembles the adult. The maxillary does not reach beyond the 
eye, the color is in more or less well-defined cross-bars, and the 
scales which in the adult are cycloid, have several large teeth, fig. 
16, pl. ili. The color under the microscope still resolves itself into 
distinct cells, fig. 17. The skull is also quite different from that of 
the adult in specimens even more than an inch long. In short, the 
young is a Godius, while the adult is a Gillichthys. 
The two species of Lepidogobius have but recently been discovered. 
The one figured (5, pl. iii) was first described from Guaymas, and 
was but the past year recorded from California waters. It was col- 
lected by Jordan and Gilbert, as early as 1880, and several speci- 
mens have also been in our collection for sometime, having been 
taken from the stomach of a larger fish. The ZL. gilberti was dis- 
covered while a Chinaman was digging for “craw-fish’’ in the 
beaches between Roseville and La Playa. In the little pools formed 
in the holes dug by the Chinaman little fishes were soon seen swim- 
ming about; all but one of them proved to be this species. Pro- 
fessor Gilbert, for whom the species was named, has since found it 
in many places along lower California, including the gulf coast. It 
is thus seen that both of these species have a wide distribution. 
Clevelandia is by far the most abundant of the gobies, and in 
fact the most abundant of any fish in the bay of San Diego. They 
are found everywhere between high and low-water mark, and 
doubtless form an important item of the food of the larger fishes; 
they spawn in the early part of May. The young, fig. 1, pl. iii, 
rise to the surface at night, and are then sometimes taken.in the 
surface dredge. They can, however, be procured more abundantly
