( -HAMiiKitMN ;: tfYRIOPODA OF THE AUSTRALIAN REGION. 93 



With numerous but not dense short straight hairs, some on last segment both 

 above and below longer than the others. 



Male gOnopodfl reserved for subsequent deseript ion. 



Number of segments, forty-eighl to fifty. 



Length, up to about 8 nun. 



A Bpecies less pigmented than the Javan 8. formosus and elegant 

 Pocock l)tit more pigmented than S. dempuramu and celeben&is Carl. 



251. Si phono its FIJIEN8IS, sp. nov. 



Type.--M.CZ. 4,584. Paratype. — 4,585. Fijis: Nansori 

 (W. M. Mann). 



This species is similar in general to S. intermedium but is larger, of a darker, 

 ferruginous color. Each somite above with somewhat darker, brownish 

 markings areolated as usual, these darker markings on all somites, not confined 

 to the anterior ones as in intermedins, and showing distinctly only under the 

 microscope. Antennae with violet-brown pigmentation over a lighter back- 

 ground. Head marked similarly to S. intermedins. 



Antennae longer than in the preceding species, with article proportionately 

 more elongate, ordinarily exceeding the head beneath by fully the last two 

 articles; more uniformly cylindrical than in the other species. Head in front 

 with numerous short hairs and two longer ones between eyes. 



The hairs of the dorsum much as in S. intermedins. The penult tergite 

 proportionately to the adjacent tergites is obviously shorter, the ratio of the 

 last three tergites to each other usually about as 6:9:7. The anal tergite 

 projects less over the valves. Prozonites in general more deeply depressed 

 than in the other species. 



The male gonopods are more prominent. The anterior pair in lateral view 

 not narrowed distad, being in fact somewhat expanded above base. Styles 

 not projecting ventrad beyond anterior gonopods, distally extending cephalad. 



Number of segments more numerous, from forty-five to sixty-seven in the 

 males. 



Length, up to 10 mm. 



252. Siphonotus solitarius, sp. nov. 



Type.— M. C. Z. 4,586. Fijis: Nansori (W. M. Mann). 



Color fulvous, darker markings vague. Violaceous dottings on antennae 

 obscure. 



Proportions of antennae and its articles nearly as in S. fijiensis. 



Prozonites less depressed than in the preceding species, the dorsal line of 

 each tergite being nearly straight. Last segment proportionately more slender.
