NO. 4 schmitt: stomatopods 219 



specimens was one of the crests armed with as many as 3 spinules, the 

 corresponding crest of the pair having one spine in one instance and 2 in 

 each of the others. Sometimes, in the case of 5 individual carinae among 

 20 odd specimens, the spine (single) arming this crest of the intermediate 

 marginal tooth is followed by a small nodular swelling, perhaps repre- 

 senting an incipient or undeveloped 2nd spine; otherwise not less than 

 half the total number of specimens had 2 spines on at least one of the 

 two crests. 



The accessory carinae are usually, or perhaps typically, armed with 

 2 spinules. Only in one instance did I observe an accessory carina in this 

 species armed with 3 spinules, and then on one side of the telson only. 

 Sometimes there may be 2 spinules followed by a nodule, or only one 

 spinule and a nodule. In 9 specimens the accessory carinae are unarmed ; 

 these are all small specimens scarcely, if at all, exceeding 30 mm. in 

 median length exclusive of rostrum. 



The lateral teeth or lobes of the telson are blunt, in no case spined, 

 and only wanting, or not much more than indicated, in four instances. 



The anterolateral angles of the rostral plate are more truly or more 

 nearly spiniform than in any of the species of Gonodactylus dealt with 

 in this account ; in only 2 specimens out of the lot are they not spiniform, 

 subacute to acute, in only one blunt; one specimen has one angle spini- 

 form, the other rounded, the only rounded angle found in any of the 

 material. 



The ocular plates are quite different from those of jestae, inasmuch 

 as the anterolateral angles are produced more or less forward instead of 

 laterally, thus making these prominences appear no wider than long; in 

 G. festae they are plainly wider than long because of the noticeably 

 laterally produced anterolateral angles. At first I believed bahiahondensis 

 represented a variety or subspecies of festae, but the almost invariably 

 consistent difference in the ocular plates of the 2 forms has led me to 

 consider them specifically distinct. 



Remarks: On the basis of the character of the ocular plates alone, 

 the Perico Island, Bay of Panama, specimen which Dr. Bigelow had 

 considered representative of G. festae is a good bahiahondensis. Also, it 

 has a two-spined "knob," and distinct submedian carinae; the crests of 

 the submedian teeth of the telson are each armed with one spine plus the 

 indication of a second, while the accessory carinae are armed on the one 

 side with 2 spines or spinules and on the other with a spine and the 

 indication of a second.
