Key to Adult Hawaiian Squillidae 
A. Raptorial claw with articulation of me- 
rus and ischium terminal (Fig. 3g), me- 
rus grooved ventrally for reception of 
propodus throughout its length, pro- 
podus finely pectinate or with a series 
of fixed spines along the upper margin, 
dactylus not inflated at base ........ B 
AA. Raptorial claw with ischio-meral arti- 
culation at a point anterior to the prox- 
imal end of the merus (Fig. 21c), ventral 
surface of merus grooved for reception 
of propodus for not more than 0.75 of 
its length, propodus may or may not be 
finely pectinate along the upper margin, 
dactylus inflated at base (Odontodac- 
tylus and Gonodactylus) .......... I 
B. Carapace with well-marked carinae , cer- 
vical groove defined across the dorsal 
surface; first 5 abdominal somites with 
longitudinal carinae (Squilla) ...... C 
BB. Carapace without well-marked carinae, 
cervical groove not extending over dor- 
sal surface; first 5 abdominal somites 
without longitudinal carinae ........ F 
C. Anterolateral angles of carapace armed 
with short, acute spines; cornea of eyes 
set obliquely on stalk (Fig. 3^), nearly 
1.5 times as wide as greatest breadth 
of stalk, distinctly bilobed. ........ .D 
CC. Anterolateral angles of carapace round- 
ed, without short acute spines (occa- 
sionally with spines in S, alhd)\ cornea 
of eyes set transversely on eyestalk (Fig. 
6), slightly wider than the greatest 
breadth of stalk, very slightly bilobed

white throughout . Squilla alba 
EE. Submedian teeth on posterior margin 
of telson without movable tips; 8 or 9 
movable spines along outer margin of 
exopod of uropod; 1 rounded lobe 
near base of inner spine of basal pro- 
longation of uropod; body with definite 
brown pigment marking carinae and 
margins Squilla calumnia n. sp. 
F. Lateral margins of exposed thoracic 
somites and abdominal somites parallel 
throughout, riot increasing in breadth 
posteriorly; telson with sharp median 
Carina and with lateral carinae (Pseu- 
dosquilla) G

abdominal somites not parallel through- 
out, abdominal somites increasing in 
breadth posteriorly; telson with median 
Carina low and rounded, and without 
lateral carinae (Lysiosquilla and Cor- 
onida) H 
G. Inner spine of basal prolongation of 
uropod longer than outer spine; eyes 
small and cylindrical; 6 carinae besides 
median carina on telson .
