NO. 4 schmitt: stomatopods 165 



Squilla tiburonensis, new name 



Squilla panamensis variety B Bigelow, Johns Hopkins Univ. Circ, Vol. 

 10, No. 88, p. 94, 1891; Proc. U.S. Nat. Mus., Vol. 17, No. 

 1017, p. 529. 



Distribution: Known only from the Gulf of California, within 

 which its known range extends from Angel de la Guardia Island on the 

 north to Espiritu Santo Island on the south. The type (U.S.N.M. No. 

 18468) is from S.E. of Tiburon Island {Albatross Sta. 3014, March 23, 

 1889, 29 fathoms). 



Color: Apart from various morphologic differences, S. tiburonensis 

 may be distinguished from S. panamensis by its different color markings : 

 basally on the telson, in place of the dark or black crescent either side 

 of the median carina, there is a dark-colored, more or less squarish area. 

 There are also a pair of squarish black areas on the middorsum of the 

 2nd and 5th abdominal somites. Although most of the articulated somites 

 of the thorax and abdomen have the posterior margin dark edged, the 

 coloration here is not so thick, dense, or conspicuous as it is in panamensis. 

 In tiburonensis there is very little dark color on the distal margin of the 

 basal (penultimate) segment of the exopod of the uropod, the terminal 

 segment or blade is in its longitudinal outer third more or less white or 

 colorless, in the other two thirds dark colored or black; the distal half 

 of the blade of the endopod is black in its outer half or little more, and 

 white on its inner half except for a narrow longitudinal black line close 

 to the inner margin of the blade. See also color notes on S. hancocki, 

 p. 162.
