56 first Annual Report 
Figures 22 and 23. The abdominal cavity is quite short, and de- 
pressed rather than compressed, except anteriorly, where it narrows 
decidedly, the liver extending well forward along the cesophagus. 
The spleen is very small, the liver large. No pyloric ceca are present. 
Food—tThe specimens dissected contained only small crustaceans 
(amphipods, ete.), no traces of plant food being found. 
Hyposoblennius gilberti (Jordan) 
(Plate II, F, and Figures 24 and 25) 
One specimen taken in a tide-pool near Laguna Beach. This 
species is reported by Starks and Morris (Marine Fishes of Southern 
California, p. 238), as abundant in the tide-pools near Point Loma 
and at San Pedro. Our observations show a decided contrast to this 
in the region of Laguna Beach, however, as only one specimen was 
obtained during the summer’s collecting. The following notes and 
figures are taken from this specimen, a female 27 mm. long: 
Abdominal cavity greatly compressed, over twice as high as broad 
in front; no pyloric ceca; liver greatly compressed, nearly as high 
as long, triangular in lateral view; its right side not developed 
apically, but stopping in a straight line back from tip, as shown in 
Figure 24. The gall bladder is not enveloped by the liver, but lies on 
the right side as indicated, being connected with the liver by a long 
neck. The alimentary canal (Figure 25) is long, being seven-eighths 
of the body length, and not distinctly differentiated into definite re- 
gions. The inner lining of the stomach is densely covered with rela- 
tively long papille, looking like minute tentacles. 
Food—Only traces of food were found. These were evidently 
plant remains, but so disintegrated as to make further identification 
impossible. 
Hypsoblennius gentilis (Girard). 
(Plate ITI, EK, G, and Figures 26 and 27) 
One specimen taken in a tide-pool near Laguna Beach, and about 
twenty-five specimens at Long Beach. The latter were found among 
green alge in some small pools at the base of a number of old piles. 
They were all livid green when taken, but soon faded to the normal 
white color with gray markings. The accompanying figures and notes 
are from the Laguna specimen, a female 37 mm. long. This individual 
contained mature ova when collected in July. 
Visceral organs and abdominal cavity much as in H, gilberti. The 
long gall bladder, peculiarly shaped liver, and the alimentary canal 
do not differ essentially from the latter, as may be seen from Figures 
26 and 27. Figure 26 gives a somewhat distorted view because of
