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 oesophagus. 

 The spleen is very small, the liver large. No pyloric caeca are present. 

 Food The specimens dissected contained only small crustaceans 

 (amphipods, etc.), 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 caeca; 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 papilla?, 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 III, E, 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 algae 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
