X, D, 8 Kemp: Stomatopod Criistacea 183 



Galera, Mindoro (Scale), April 15, 1912, 1 ?, 32 mm. No. 0-1088. Tay-

The majority of the above specimens belong to form B, which 

 Borradaile names "var. rotundus." One specimen, however, is 

 of the narrow-keeled type, form A (= var. ternatensis de Man), 

 and one, in which the keels of the telson are swollen, but possess 

 prominent terminal spines, is intermediate between the two 

 forms.

No. 0-652. Port Galera, Mindoro (Cowles), 2 c?, 3 ?, 12-15 mm. 



The carapace is longer than broad, with the posterior margin 

 concave. The anterior margins on either side of the rostrum 

 are straight, but slope strongly backward toward the antero- 

 lateral angles, which are subacute and slightly produced (fig. 9). 

 The rostrum is sharply trispinous ; the basal portion from which 

 the spines arise is remarkably short, its length being less than 

 one quarter its breadth. The 2 anterolateral spines are strongly 

 curved and but little stouter than the central spine, which reaches 

 at least to the middle of the eyestalks. 



The dorsal processes of the ophthalmic somite are visible be- 

 tween the rostral spines (fig. 9). They are small and wing- 

 shaped, with straight anterior margins and a lateral margin that 

 slopes inward posteriorly; the anterolateral corners of the pro- 

 cesses reach to a point midway between the median and lateral 

 rostral spines on either side. The eyes are cylindrical and extend 

 a trifle beyond the second segment of the antennular peduncle; 

 the cornea in dorsal view is not wider than the stalk. 



The mandibular palp appears to be wholly absent. 



The dactylus of the raptorial claws resembles that of G. ne- 

 fandus and is less strongly swollen than in G. pulchellus; at its 

 proximal end it is distinctly notched externally. 



The lateral margins of the exposed thoracic somites are 

 rounded ; the posterolateral angle of the third abdominal somite 

 is rectangular, those of the fourth and fifth somites subacute. 

 Each of the first 4 abdominal somites is grooved close to the 

 lateral margin, and inward from this groove a small dimple or 

 depression is visible; the median portions of the somite are in 

 every case quite smooth. The fifth somite is feebly ridged long- 

 itudinally on either side, but in the middle is quite smooth" (fig. 

 10) , in this respect differing from the allied species, G. tuber osus 

 and G. trispinosus. On the last abdominal somite the usual 

 transverse row of 6 large tubercles is distinct. 



The telson is almost circular in shape and bears in the anterior
