NO. 4 schmitt: stomatopods 153 



Zone, collected March 3, 1937, by Dr. S. F. Hildebrand, for whom I 

 take pleasure in naming the species. 



Description: A species with strong Indo-Pacific affinities, inasmuch 

 as it is in many particulars very close to S. hieroglyphica Kemp^^ and, 

 like that species, near S. laevis^^ Hess. As in both these species, the man- 

 dibular palp is entirely missing. 



Of the several Pacific-American species here dealt with, it has, next 

 to S. panamensiSj the most roughly surfaced carapace. This, although to 

 all appearances smooth and shining, is finely pitted or punctate, eroded 

 much as in S. panamensis, but not as coarsely so, yet more so than the 

 other west coast species of Squilla. 



The anterior width of the carapace is nearly % its median length 

 exclusive of the rostrum, much as it is in hierofflypha,^^ where the ante- 

 rior width equals 34 tbe median length ; in laevis the carapace is stouter, 

 the anterior width being half the length of the carapace including the 

 rostrum. The lateral margins of the carapace are not angulated before 

 the rounded posterolateral angles. The median carina is distinct before 

 the dorsal pit but, as in hieroglypha, not bifurcate, while in laevis it is 

 bifurcate; the intermediate carinae are distinct but short, anterolateral 

 spine present, of good size. 



The rostrum is wider than its median length and in shape more or 

 less intermediate between laevis and hieroglypha; it is carinated as in 

 the latter, but the median carina runs closer to the tip, where a small 

 gap intervenes between the anterior ends of the marginal carinae and also 

 the end of the median carina. 



As in hieroglypha and also S. aculeata, the cornea is more or less 

 transversely placed on its triangular stalk; in our species the eyestalks 

 are of a rich golden brown color ; each stalk, as in hieroglypha, carries 3 

 prominent spots arranged in the form of a triangle. 



As in hieroglypha also, there is no spine at the distal end of the in- 

 ferior margin of the propodus as in laevis; and, like the former species, 

 ours has the raptorial dactylus armed with 5 teeth, including the termi- 

 nal ; in laevis there are 4. 



The lateral processes of the 5th thoracic somite are in size, shape, 

 and direction more or less intermediate between hieroglypha and laevis;

■*i Not including the rostrum, as in Kemp's text, for in his figure the anterior 

 width equals about ^ the median length exclusive of the rostrum.
