NO. 4 schmitt: stomatopods 143 



G^. Eyestalks dilated, bottle or flask shaped, distally constricted 

 before cornea; cornea set more or less obliquely on eye- 

 stalk, major axis of cornea shorter than the peduncular one 

 extended to anterior margin of cornea. 



Raptorial dactylus with 5 or 6 teeth. Median carina of carapace 

 not bifurcate, intermediate carinae fall well short of anterior 

 margin. Lateral process of 5th thoracic somite a sharp spine to 

 side, slightly inclined forward, lateral margins of 6th and 7th 

 angled and medially emarginated, suggestively but not definitely 

 bilobed. Epipodites on first 3 thoracic limbs. Prelateral lobe or 

 angle of telson not spined. Denticles 1-3, 3-4, 1. . dubia, p. 155 



G^. Eyestalks triangular or subtriangular, widest distally next to 

 cornea, corneal axis at least as long as, usually longer than, 

 peduncular axis. 



Raptorial dactylus with 6 teeth. Lateral margins of 6th and 7th 

 (at least 6th) thoracic somites usually more or less distinctly bi- 

 lobed. 



Di. Prelateral lobe or angle of telson present and spined. 



Submedian carinae of 5th and 6th abdominal somites, and usu- 

 ally also 4th in all specimens exceeding 65 mm. in median 

 length exclusive of rostrum and occasional smaller ones, poste- 

 riorly spined. Median carina of carapace bifurcate anteriorly 

 and if bifurcate posteriorly before the cervical groove only 

 inconspicuously or incompletely so; intermediate carinae run 

 to or about to anterior margin. Lateral spine of 5th thoracic 

 somite stout, markedly turned forward; posterior lobe of later- 

 al margin of 6th and 7th somites subacute or acute, more or 

 less laterally directed. Cornea set very obliquely on eyestalk. 

 Epipodites present on first 5 thoracic limbs. Denticles 4-6, 7-9, 

 1 biffeloivij p. 156 



D^. Prelateral angle of telson margin, if present, not spined. 



E^. Of submedian carinae on the abdomen only those of the 

 6th somite are posteriorly spined. 



F^. Median carina of carapace before level of cervical 

 groove more or less distinctly bifurcate at its an- 

 terior and posterior ends; intermediate carinae 

 fall well short of anterior margin.
