NO. 4 SCHMITT : STOMATOPODS 197 



crowded with chromatophores. The uropods have the terminal blade of 

 the endopod well sprinkled with chromatophores, though well spaced 

 and distinct ; in the figured type these blades are without chromatophores. 

 The dense black median area figured by Coutiere is not much in evidence, 

 although the telson has a medially placed dark patch of aggregated chro- 

 matophores. Not apparent in the type, the posterior median portion of 

 each of the abdominal somites except the last carries a subrectangular 

 patch of black chromatophores, in contact with the black posterior margin 

 of each somite and extending forward from % to % the median length 

 of the somite; before this squarish patch the middorsum of each somite 

 is without color markings. 



There are differences in the armature of the telson of the broken 

 young male due to its immaturity. There are a greater number of low 

 projections across the postdorsum of this specimen than there are spines in 

 the corresponding area in the type and in the female, which is like the type 

 in this respect. The submedian spinules of this "littoral stage" of the male 

 between the movable submedian spines arising from the under side of the 

 telson are 14 in number. In some ways this transverse row of submedian 

 spines is reminiscent of that in L. decemspinosa, a stomatopod probably in 

 the littoral stage. Aside from other differential characters, the two may 

 at once be distinguished by the conformation and spination of their rostral 

 plates. The raptorial claws of this juvenile male seem to be identical with 

 those of the figured type. The lateral rostral teeth are slightly shorter 

 than the median one. The shorter rami of the 7th thoracic legs are the 

 most broadly oval, the 6th next in width, and the 8th the narrowest ; in 

 the type the shorter rami of the 8th pair of thoracic legs also appear to 

 be the narrowest of the 3 pairs and the 7th broadly oval or subcircular. 



Lysiosquilla mccullochae, new species 



Distribution: Known only from the unique female holotype 

 dredged from a coralline algal bottom in 30 fathoms off San Francisco 

 Island, Gulf of California, February 24, 1936 (Hancock Exped. Sta. 

 513-36). 



Size: The type measures on the median line, exclusive of rostrum, 

 about 32 mm., carapace 7, rostrum 1.9. 



Description: Carapace smooth, anterolateral angles broadly round- 

 ed; the slight depressions at about % the length of the carapace from its
