Phlyxia and TJtica (Has well), and exist in Australian waters 

 now. TJtica are very numerous, Phlyxia scarce. At present 

 I can only forward examples of TJtica Yarraensis (Wintle), 

 but hope to be able to supply specimens of Phlyxia. 



DESCRIPTION. 



TJtica Yarraensis (Wintle), carapace sub-quadrate, smooth, 

 naked, rounded, convoluted, trilobed, anterior margin nearly 

 straight. Anterolateral margin with one small conical tooth 

 in living examples. Posterior margin unarmed. Postero- 

 lateral margin edges recurved. Eye-stalks short, depressed. 

 Ambulatory appendages fine, tomentose, terminal, and penul- 

 timate ; joints fringed below with fine hairs ; jaw legs long, 

 slender, second joint twice as long as first one. Jaws slight, 

 attenuated. Abdomen without deep mesial furrow. Third 

 and sixth segments coalescent in both sexes. 



Shores of Port Phillip, Port Jackson, and possibly 

 Tasmania. 



TJtica Haswelli (Wintle), carapace subquadrate, broader 

 than long, smooth, convoluted, trilobed. Anterior margin 

 shield-shaped, edges finely recurved. Two deep lateral 

 furrows. Ambulatory appendages finely tomentose, long, 

 same as in 77. Yarraensis. A close ally to 77. barbimana 

 (Has well). 



Associated with these crabs are the remains of the small 

 freshwater crayfish, Astacopsis Franhlinii (McCoy) ; the river 

 mussel, TJnio sp., both of which have been brought down 

 from the fresh water by river action, and with them are also 

 found marine testaceous remains in abundance. (See 

 examples.) 



I purpose at a future early date sending further examples 

 from this interesting deposit, with diagrams of section of the 

 stratigraphy of the canal cutting.
