NO. 4 schmitt: stomatopods 199 



posterior margin in the distinct gastric grooves are suggestive of indica- 

 tions of a cervical groove of which, however, there is no trace across the 

 middorsum of the carapace. The cornea is large, wide, somewhat obscure- 

 ly bilobed, and set more or less transversely on its stalk ; its transverse axis 

 is about as long as the visible portion of the median longitudinal axis of 

 the stalk if continued across the cornea; the cornea overhangs the inner 

 and outer borders of the stalk. 



Median length of rostral plate about % its greatest width. Antenna! 

 peduncle and antennal scale each exceeding cornea and reaching about 

 as far forward as the proximal border of the terminal segment of the 

 antennular peduncle. Mandibular palp 3-segmented. 



Upper border of the raptorial carpus not carinate, but dorsal margin 

 terminates anteriorly in a more or less acute spine ; on the inner side of the 

 propodus below the pectinate margin are 4 movable spines, the first and 

 longer 2 are near the carpal end, the somewhat shorter 3rd and 4th are 

 situated at about the carpal ends of the pits in which the penultimate and 

 antepenultimate dactylar teeth become concealed when the dactylus is 

 tightly closed against the propodus. The dactylus is armed with 4 teeth, 

 including the terminal one; at its base externally there are 2 lobes of 

 which the first, or proximal one, forms almost a blunt right angle, the 

 second is broadly rounded off. The chelae of the 3rd thoracic limbs are 

 perhaps % the size of the 4th, while those of the 5th pair are scarcely % 

 the size of the 3rd pair. 



In dorsal view, the lateral margin of the 5th thoracic somite is plainly 

 bilobed ; the lobe at the anterolateral angle appears almost tuberculiform, 

 while the posterolateral angle, on the other hand, is seemingly drawn out 

 to a blunt point directed laterally downward ; the margin of the 6th and 

 7th somites laterally are squared off. The distalmost of the 2 joints of the 

 shorter ramus of the 5th and 6th pairs of thoracic feet is somewhat 

 broadly ovate, the 6th more so than the 5th, while the 7th is more linear, 

 yet bladelike, though parallel sided. 



The abdominal somites are all dorsally smooth, with posterolateral 

 angles rounded, except the 6th, which has the posterolateral angles each 

 armed with a sharp spine, and the dorsal surface obsolescently, very shal- 

 lowly and broadly corrugated longitudinally, most noticeable in the lon- 

 gitudinal depression near each raised-up lateral margin. There is a second, 

 less noticeable pair of depressions, one on each side separated from its 

 deeper corresponding lateral depression by a low, blunt, more or less 

 longitudinal swelling.
