N0 - 36" STOMATOPOD CRUSTACEA — MANNING 31 



Kemp (1913, p. 68) also noted that his specimens from Mauritius 

 resembled material from Hawaii, which shared the distinctive features 

 mentioned above. The form from Hawaii is another distinct species 

 the description of which is in preparation. 



Sguilla mauritiana agrees with S. oratoria in having the median 

 carina of the carapace uninterrupted; that character will distinguish 

 both species from S. fabricii Holthuis, S. inornata Tate, S. interrupta 

 Kemp, and S. perpensa Kemp. Sguilla woodmasoni, S. hesperia, and 

 S. massavensis, other species of the "oratoria complex" that occur in 

 the western Indian Ocean, lack the anterior bifurcation on the median 

 carina of the carapace; S. woodmasoni has a much broader carapace 

 and smoother telson than either S. hesperia or S. massavensis. Manning 

 (1968) outlined the diagnostic features of several of the species in the 

 "oratoria complex." 



Distribution. — Indian Ocean, from Mauritius, and Madagascar.
