antenna. Menzies and Barnard did not include a 
picture of the male second pleopod with the 
description of the holotype and they pictured 
the first antenna incorrectly. The first antenna of 
the male specimen examined had 12, not 9, 
flagellar articles as stated in the holotype de- 
scription; and the holotype description should 
be amended to read 12 flagellar articles in the 
first antenna, since other specimens were ex- 
amined (male and female) and they had 12 
flagellar articles.

Fig. 4 
DIAGNOSIS: Body pigmentless. Eyes present, 
composed of five to seven ocelli which are 
pinkish in alcohol preserved specimens. Peraeon 
smooth, without pits or keels. Rostral projection 
of cephalon not as far forward as anterior ex- 
tent of anterolateral margins. Seventh peraeonal 
segment about half length of sixth segment. 
Pleonal segments distinct. Telson with paired 
statocysts, rounded with small dent in tip bear- 
ing several large, stiff setae. Peraeopod one sub- 
chelate; both peraeopods one and two with car- 
pus attached under propodus. Peraeopods three 
to seven also with carpus under propodus, but 
not as apparently so. Seventh peraeopod with 
small ungus; dactylus covered with scalelike 
rows of setae; propodus with sensory setae near 
dactylus. Antennae one and two pauciarticulate 
each with five segments; large tufts of setae on 
apical segments of each antennae. Maxilliped 
with five (four free) segments. Third segment 
with ventrally projecting setae, apical segment 
smallest with large medially projecting setae. 
Uropodal endopod longer than telson. Telson 
and both uropodal rami with row of many setae 
along minutely serrated margins. 
MEASUREMENTS: Holotype female, 11 mm 
long. 
TYPE LOCALITY: 2998; Feb. 6, 1955; approx. 
80 m; 9-9 miles SSW of Santa Monica Pier; 
taken from black mud. Lat. 33°-53'-22", long. 
118°-34'-40". 
MATERIALS EXAMINED: Twelve female speci- 
mens, from several to 11 mm long. 
DISTRIBUTION: Known only from type lo- 
cality. 
AFFINITIES: A. calif orniensis, n. sp., is most 
like A . senegalensis Barnard (1925) except that 
it does not have large eyes. Both species have 
pauciarticulate flagella with several bushlike 
groups of setae.
