I. zimmeri Stebbiug, 



uropod. 



rounded _clistal process simulating and perhaps representing a short 3^ joint. 

 Peduncle of uropods subequal to the rami; endopod with V^ joint much 



stouter than 2^^, about half as long, 



fringed on medial margin with 10 



pectinate spines, the apical much the 



longest, 2"^* joint fringed with a dozen 



spines, the lowest the largest, follow- 

 ed by an oblique series of lOspinules 



extending to the acute apex which 



carries an inward pointing spine. L. 



9 mm. A specimen without pleopods, 



L. 5 mm, agrees as to the uropods 



with I. rohusta, H. J. Hansen (nr. 7).

Pseudorostral lobes rather short, horizontal, acute at apex, then truncate, 

 then emarginate; antero -lateral corners acutely produced in 9 . Carapace 

 very slender, nearly three times as long as high, lower margin for a short 

 space anteriorly serrate, otherwise quite smooth, with no distinct median 

 carina, which is confined to the pleon segments, but sometimes having a 

 longitudinal medio-dorsal row of denticles beginning behind the eyelobe and 

 extending half the length of the carapace (Zimmer) ; the pedigerous segments 

 quite smooth. Eyelobe rounded, eye darkly pigmented, corneal lenses indistinct. 

 Antenna 1. 3^ joint longer than '2''^. Antenna 2 in 9 1-jointed, with 3 or 4 

 plumose setae, in 6 reaching to end of pleon. Maxilliped 3, 2''^ joint unusually 

 long, but distal process moderately produced, rest of limb little more than 

 one-third as long as 2"^ joint, 4*^1 joint moderately produced, 5*^11 not specially 

 widened. Peraeopod 1, 2«'i joint considerably longer than rest of limb, 7^^ joint 

 nearly equal to 6*^. Peraeopod 2 very short, shorter than peraeopod 3, 

 2^^ joint abnormal, little longer than broad, the next joint with strong spine 

 on produced truncate apex, 3^ joint wanting. Peduncle of uropods in imma- 

 ture Q equal to, in 6 adult longer than the equal rami, exopod robust, with 

 numerous setae on margins and blunt apex, endopod in d with 1^* joint little 

 longer than broad, about half as long as the narrow second joint, carrying 

 short spines on medial margin and a long apical spine, the 2"*^ joint fringed 

 with spines successively larger to the long terminal spine. Colour a clear, 

 almost pellucid, grey. L. d adult 8*6 mm, 9 immature 6-6 mm, 9 ovigerous 

 about 12—18 mm, d adult 15 mm.
