144 FISHES OF SAN DIEGO—EIGENMANN. 
SYNGNATHIDA. 
I have little to say concerning the members of this family. They are 
always very abundant, but I have observed them only once or twice 
while with the seiners, and while skimming for pelagic eggs. 
Siphosotma punctipinne (Gill). 
Gill, Proc. Acad. Nat. Sci., Philad., 1862, 283; J. & G., ’81, 69; id., ’82, 385; R. 
Smith, ’85, June. 
Only the types known. 
Siphostoma auliscus Swain. 
R. Smith, ’85, June. 
Common. 
Siphostoma leptorhynchum Girard. 
Girard, Pacific R. R. Survey, x, 345, 1859. J. & G., ’80, 23; R. Smith, 780; J. 
& G.. ’80a, 453; July, 81, 69; id., 82, 384; R. Smith, ’85, June. 
This is by far the commonest species of pipefish in the bay. Several 
are always taken in summer with the dredge, while the seine always 
brings them. 
Hippocampus ingens Girard. 
Girard, Pacific R. R. Survey, x, 343, 1859. J. & G.,’80, 23; R. Smith, ’80; J. & 
G., ’80a, 453; id., ’81, 69; id., 82, 386; R. Smith, ’85, June. 
We have never taken this species and have seen no specimens which 
certainly came from San Diego. It is said to oceur about the Coronado | 
Islands. 
GASTEROSTEID &, * i 
Gasterosteus microcephalus Girard. 
k. Smith, ’85, June. 
This species has not been observed by us during the year. It was 
taken by Rosa Smith in Wildeat Caiion, a tributary of the Tia Juana — 
River. : 
MUGILID&. . 
Mugil cephalus L. 
Steind., Ichthyol. Britr. III, 58, 1875; J. & G., ’80, 29; R. Smith, ’80; J. & G., 
80a, 457; id., 81, 76; id., ’82, 403; R. Smith, ’85, July. 
This species becomes abundant about the middle of February. It 
then enters the bay and ascends the swollen coast streams. The — 
exact time of spawning has not been determined. One ripe female was — 
reported to us on December 10 by a fisherman, who had never noticed : 
it with eggs at other times. The young remain in the bay throughout 
the year, and are found chiefly in the sloughs of mud flats.

seen it.
