is not yet represented in any local collection. It is quite possible that it 

 may occur in the northern part of New Zealand, and the recent rediscovery 

 of some of the species assigned to New Zealand by Heller which were 

 thought at one time to be errors makes it desirable to keep this species 

 still on the list as a possible occasional visitant to New Zealand seas. 



Genus Squilla Fabricius. 



Diagnosis. — " Stomatopoda having the telson attached to the 6th ab- 

 doniinal segment by a movable joint ; the hind-body depressed and wide ; 

 the dactylus of the raptorial claw with usually not more than 6 teeth ;

 usually longer than Made : and the inner basal spine of the uropod the longer

 terior lateral lobes, anterior 

 lateral angles produced 

 into acute spines ; lateral 

 spines of the 5th thoracic 

 segment narrow, straight, 

 and acute, the lateral pro- 

 cesses of the next two 

 segments broadly rounded 

 and produced into spines 

 that point backward ; 8

 segments ; telson with a 

 crest and a keel and a

one." (Bigelow.) 



Length of largest specimen examined, 135 mm. ; usual length, 60-80 mm. 

 This species is probably common in New Zealand seas, though it is only 



occasionally met ^vith, most of the specimens- in local museums having
