PACIFIC SCIENCE, Vol. VII, October, 1953 
an acute, anteriorly directed process, sixth, 
seventh, and eighth narrowed but evenly 
rounded (Fig. 16); dorsal surface of sixth 
abdominal somite ornamented with a scroll- 
like series of tubercles (carinae.^), nearly sym- 
metrical in arrangement. Telson with a series 
of similar tubercles which may be unsym- 
metrical except in the median region (Fig. 
16); posterior border medially notched giving 
the appearance of two rounded lobes, with a 
pair of submedian spines and four to six mar- 
ginal spines lateral to each submedian. Exo- 
pod of uropods with 8 to 11 movable spines 
on outer margin; elongated basal portion of 
uropods with two spines, inner longer than 
outer. First abdominal appendage of female 
shown in Figure 17^. Living animals are trans- 
parent white, preserved specimens opaque 
white throughout. Specimens range from 9-5 
to 17.0 mm. in length. 
DISCUSSION; Three female specimens of this 
small species have been examined, including 
the type specimen in the Bishop Museum. 
All had been collected from among dead coral 
on Waikiki Reef, Oahu. 
The species is apparently closely allied to 
Coronida fmdtituherculata (Borradaile) (1898), 
but differs considerably in the shape of the 
rostrum and in the ornamentation of the sixth 
abdominal somite and telson. 
Specimens may be easily recognized by the 
ornamentation of the last two body segments. 
The tubercles (or carinae as they are called by 
Edmondson) of the sixth abdominal somite 
form a definite pattern which is nearly sym- 
metrical on each side of the median line, 
suggesting a single median carina, paired sub- 
median carinae, paired intermediate carinae, 
paired lateral carinae, and paired marginal ca- 
rinae. The telson is similarly ornamented, but 
is not usually as symmetrical as shown in 
Figure 16. Here there is also a suggestion of 
a median carina, paired submedian carinae, 
and paired intermediate carinae; but all are 
somewhat joined to one another forming a 
scroll-like pattern. There appears to be con- 
siderable variation in the number of spines 
found on the posterior margin of the telson, 
and I am inclined to believe that there is but 
a single pair of submedian spines, the rest 
being small, marginal denticles, although Ed- 
mondson (1921) recognized two other pairs. 
The slightly inflated base of the dactylus 
suggests affinities to Gonodactylus and Odonto- 
dactylus, but the articulation of the ischium 
and merus of the raptorial claw indicates a 
close relationship to Squilla, Pseudosquilla, 
and Lysiosquilla. 
Because of their very small size it can be 
seen why this species has not been collected 
more often. The three specimens which I have 
examined ranged from 9.5 to 17.0 mm. from 
the tip of the rostrum to the distal end of the 
submedian spines of the telson. Living adults 
are also very transparent and difficult to see.
