TERRESTEIAL LSOPODA OF \EW ZEALAND. 127 



fourth, slightly sinuous, narrowed at base ; flagellum as long as the fourth joint, stout, 

 comjiosed of four joints, the first two short, suhoqual, third longer, fourth very short, 

 articulations not very distinct ; whole antenna roughly granular, with very few setaj. 

 Legs rather short, not visible in dorsal view, and not increasing in length posteriorly. 



Pleopoda apparently as in Ormciis, opercular plates with outer margin incurved but 

 not so abruptly notched as in Oiiisciis; no air-cavities. Uropoda with the base large 

 and meeting in the median line, lateral portion expanded, flattened and keeled externally, 

 ending acutely external to the outer ramus ; both rami exposed, inner ramus arising a 

 little anteriorly to the outer, but extending backwards to the same point, but with apex 

 rounded and with a very few minute setae. 



Colour brown. 



Length 20 mm., breadth 9 mm. 



Habitat. — Auckland Island {Mr. Jeniiiricj.s). 



RenKo-kx. — The above description is taken from a female, the only specimen I have 

 seen. According to Mr. Thomson the male has the whole surface of tlie body nearly 

 smootb. 



I refer Pilhol's Oniscus novfe-zeuIaudicB to this species with considerable doulst, for 

 his description and figui"e are hardly sufficient to permit of certain identification. 

 However, some points in his description as to the antennae and uropoda, and especially 

 that of the tubercles — " les granulations de la rangec posterieure sont plus detachees et 

 leui'sommet \m pen aigu est dirige en arriere " — apply exactly to the species in question. 

 He states that his specimens were obtained near Wellington. 



I have jilaced the species under ScijpJia.r only provisionally, for I have had only one 

 specimen and have not been able to examine all the mouth-parts, &c. It can hardly 

 come under Actcscia, in which it was placed by Mr. Thomson, and though it has con- 

 siderable resemblance to Oniscus, it differs markedly from that genus in the antenna} 

 and uropoda, and also in the maxillipedes, for these, as shown in fig. 2 m.ip., have the 

 terminal part well developed, much longer than the masticatory lobe, and with clear 

 indications of the joints of which it is composed. In this, and in the maxilhe which I 

 have also been able to examine, the species reseuables Scyphax, and I think it will 

 certainly come under the same family, but ifc differs greatly from -Scj/jV/ca' in the cephalon 

 and in the much smaller eyes. It prol)ably lives on the sea-shore like the rest of the 

 Scyphacida-. 



Genus 2. Scyphoniscus (novum). 

 Generic Characters. — Body rather narrow, lateral parts not greatly developed. 

 Cephalon with large broad lateral lobes. Metasome abruptly contracted, first tuo 

 segments rather short, third to fifth with small epimera, last segment short, triangular. 

 Eyes of moderate size, sublateral. Antennulae of three joints, the last small, but bearing 

 two or three sensory setse. Antennae with the flagellum of three ill-defined joints. 

 Mandibles with a membranous hairy lappet behind the two dentate lamellaj, followed by 

 a long recurved brush-like seta ; molar process represented by a dense tuft of recurved 

 setae of unequal lengtli. Anterior maxilla; with the outer lobe rather weak, some dentate
