Laguna Marine Laboratorp 33 
specimens are found, some ranging to over a foot in length. The 
older ones, however, do not commonly remain in the pools, but live 
in deeper water around the rocks and beds of alge. In individuals 
over three or four inches in length the light spots on the sides are 
obsolete. 
Many specimens of various sizes were taken. The accompanying 
figures and notes were made from a specimen 220 mm. in length. 
Figure 7 shows the contents of the body cavity with all the organs in 
their natural position. The great number of pyloric ceca, and the 
long convoluted alimentary canal are very conspicuous features, re- 
lating to the food habits of the species. Figure 8 (reduced to one- 
half the scale of Figure 7) is an outline of the alimentary canal, 
removed to show the nature of the convolutions. Corresponding 
numbers in the two figures refer to corresponding parts of the canal. 
The stomach is not so conspicuously differentiated from the rest of 
the canal as it is in many of the lower fishes previously noted. As 
seen by the figure, the @sophagus, stomach, spleen, ete., are all cov- 
ered ventrally by the intestine, which winds back and forth in a 
devious course below them. Instead of extending in a series of turns 
from the anterior to the posterior regions, the intestine appears well 
back (Figure 7 I) and after doubling across and back it makes a 
sharp turn (2 and 3) and then runs well forward around its last turn 
to (4) where it makes another sharp turn anteriorly (5), crossing 
over near the liver (6) and then down along the left side (8) to the 
anus. In Figure 8 the liver and gall bladder are shown separated 
from the rest. The gall bladder lies far back near the urinary 
bladder in the posterior part of the abdominal cavity, and is con- 
nected with the liver by its long, tube-like duct. 
The alimentary canal in this specimen measured 550 mm. in 
length, or two and one-half times the total body leneth of the fish. 
The food, as one would expect, is entirely vegetable, so far as known. 
Specimens dissected contain only pieces of kelp, red alge, ete. One 
large specimen twelve inches long had eaten several large chunks of 
kelp several centimeters in length.
