PHOTIDAE 237 



stouter, especially the terminal one. Uropod 3, inner ramus reduced to a minute 

 conical projection, which does not appear to be articulated with the peduncle, tipped 

 with one spinule. 



Colour (as preserved), white speckled with greyish, the head darker, a dark medio- 

 dorsal spot on each peraeon and pleon segment, the posterior ones more prominent than 

 the anterior ones. 



Remarks. The above description points out the differential features between this 

 form and the form referred to harbimanus . They may seem to be trivial. They may prove 

 to be merely varietal. But in practice the two forms are easily distinguished and they 

 may be separated without any reference to the respective localities. 



I suspect that this species may be very closely allied to, but not identical with, 

 Chilton's Corophium lendenfeldi (loc. cit.) which has been united with harbimanus, 

 albeit without any really critical examination. 



The difference between lendenfeldi and robusta lies in the 3rd to 5th peraeopods, 

 which in the latter are even stouter than in Chilton's figure, and the 2nd joints are 

 differently shaped. Chilton says the 3rd~5th peraeopods are "similar in form. . ., the 

 basa much expanded". It is a task for some New Zealand carcinologist to rediscover 

 lendenfeldi and give a more detailed description of it, and contrast it with the true 

 barbimanus from which I feel sure it is distinct. 



Genus Kuphocheira, Brnrd. 

 Barnard, 1931, p. 429. 



Ocular angle of head not prominent, post-antennal angle obsolete. Side-plates 

 moderate, 1st much smaller than 2nd, 4th with hind margin not excavate. Telson 

 rounded, broader than long. 



Antennae 1 and 2 short, 1st longer than 2nd, flagella shorter than peduncles, no 

 accessory flagellum. Upper lip rounded. Lower lip broad, inner lobes almost as large 

 as outer lobes, mandibular processes blunt. Third joint of mandibular palp shorter than 

 2nd. Maxilla 1, inner lobe with six setae, outer with nine spines, 2nd joint of palp 

 moderately long. Inner lobe of maxilla 2 fringed on inner margin. Maxilliped, inner 

 plate well developed, outer narrow, palp long. 



Gnathopod 1 simple. Gnathopod 2 simple, 5th and 6th joints enlarged, more so in 

 <S than $, very setose, finger reduced. 



Peraeopods 1 and 2, 2nd joint ovate, glandular, dactyl long. Peraeopods 3-5 

 increasing in length, 5 much the longest, 2nd joint oval, dactyl short. Uropods 1 

 and 2 spinose, a strong spine on lower apex of peduncle. Uropod 3 uniramous, the 

 ramus spinose. 



Peduncle of pleopods short, stout. Branchial lamellae narrow, elongate, simple. 



Remarks. Close to Haplocheira, but without accessory flagellum, with reduced finger 

 on gnathopod 2, uropod 3 uniramous, and without hooks on telson.
