no. 3G4i STOMATOPOD CRUSTACEA — MANNING 27 



slender, triangular, directed laterally; lateral process of sixth somite 

 bilobed, both lobes triangular, anterior lobe shorter and much slen- 

 derer than posterior; lateral process of seventh somite bilobed, anterior 

 lobe obtuse, smaller than that of sixth somite, posterior lobe as long 

 as but broader than posterior lobe of sixth somite; ventral keel of 

 eighth somite low, rounded. 



Abdomen with 8 carinae on first 5 somites, 6 on last, submedians 

 subparallel on each somite; second to fifth somites with anterior pair 

 of tubercles lateral to intermediate carinae; abdominal carinae spined 

 as follows: submedian, 4-6; intermediate, 3-6; lateral, 1-6; marginal, 

 1-5; sixth somite with sharp ventral spine on each side in front of 

 articulation of uropod. 



Telson slightly longer than broad, with 6 sharp marginal teeth, each 

 with short dorsal carina; prelateral lobe present; anterior portion of 

 median carina flanked by 2 short, oblique carinae at level of sub- 

 median carinae of sixth somite; median carina interrupted anteriorly, 

 terminating posteriorly in slender spine overhanging 2 tubercles; 

 convergent line of pits lateral to median carina marked by mesial 

 tubercles at middle of telson, mesial carina distally; remainder of 

 dorsal surface of telson smooth, convergent rows of pits neither in 

 well-marked grooves nor separated by carinae or low ridges; denticles 

 rounded, subequal, 3, 8, 1, each with proximal dorsal swelling; ventral 

 surface of telson with postanal keel. 



Proximal segment of uropodal exopod with 7-8 graded, movable 

 spines, last short, not extending to midlength of distal segment; lobe 

 on outer margin of inner spine of basal prolongation rounded, pro- 

 jecting slightly, margin concave. 



Color. — Antennal scale outlined in dark pigment; carinae of body 

 dark; last 3 thoracic and first 5 abdominal somites with dark posterior 

 fine; telson with dark bar across surface, distal portion of median 

 carina and marginal carinae dark; distal half of proximal segment and 

 inner half of distal segment of uropodal exopod black; distal half of 

 uropodal endopod black. 



The color pattern is very similar to that found in S. massavensis 

 Kossmann. 



Size. — Female holotype, only specimen examined, TL 116.6. Other 

 measurements: carapace length 23.3; cornea width 6.4; rostral plate 

 length 4.0, width 4.0; telson length 21.1, width 20.2. 



Discussion.— Squilla hesperia closely resembles S. inassavensis 

 Kossmann, from the Red Sea but differs in having the rostral plate 

 shorter and broader, in having the submedian carinae of the abdomen 

 divergent on each somite rather than subparallel, and in having many 

 less dorsal tubercles on the telson. Squilla massavensis has two sub- 

 median rows of tubercles converging distally on the median carinae of
