Crustaceans from Interior of Australia.— Chas. Chilton {Trans. 

 R. Soc. Australia.. 1917, 41, -475-82, 7 tigs.)- A small collection included 

 HemiporceUio strzeJecki sp. n., Cubaris daytonmsis sp. n., Apus austra- 

 liensis, Estheria pacJcardi, a species of Boeckella, and a few other forms. 

 Collectors of small Crustacea are advised to take samples of dried mud 

 from the water-holes and hatch out the Crustacea at leisure. " This 

 would be easier and more likely to lead to the discovery of new forms 

 than trying to collect the animals on the rare occasions when the 

 explorer finds the pools are full after rain." J. A. T. 



Fossil Species of Phreatoicus. — Chas. Chilton {Journ. R. Soc. 

 N.S. W., 1918, 51, 865-88, 18 figs.). From shales near Sydney, belonging 

 to Trias-Jura, or perhaps Upper Trias, R. J. Tillyard obtained several 

 specimens of a fossil Isopod, which he provisionally named Phreatoicus 

 ivianamattensis sp. n. This is confirmed by Chilton, who places the 

 fossil species near P. austraUs. The genus belongs to a primitive group 

 of Isopods. J. A. T. 



Australian Isopods. — Chas. Chilton {Trans. R. Soc. Australia. 

 1917, 41, 891-404). A survey is taken of the Australian species of 

 Serolis, including S. bakeri sp. n., near S. minuta. The genus is marked 

 by the much depressed body, circular or oval outline, and widely 

 developed epimera. The first peraeon segment has the epimeral portion 

 very largely developed and produced forwards so as to enclose the head- 

 shield on both sides. A description is given of the hitherto unknown 

 adult male of Deto marina Chilton. J. A. T. 



Respiratory Mechanism of Shore-crab. — Robeet K. S. Lim (Proc. 

 R. Soc. Edinburgh, 1917-18, 38, 48-56). The direction of the respi- 

 ratory current in Carcinns msenas is postero-anterior, whether the crab 

 is above the sand or buried in it. But reversal may occur, more 

 frequently when the crab is buried, or when a strong ink suspension is 

 used in experiment. The sub-branchial cleft may be divided into four 

 separate spaces which are in direct communication with gaps between 

 certain gill-origins, the whole constituting the sub-branchial inlets, the 

 direction of which determines the direction of the inhaled currents. The 

 relation between the position of the gills and these inlets allows for a 

 convenient and maximal flow. J. A. T. 



New Isopod from British Guiana. — Walter E. Collinge {Journ. 

 Linn. Soc. ZooL, 1918, 34, 61-3, 1 pL). A description is given of 

 Paracubaris spinosus g. et sp. n., a terrestrial Isopod, one of the 

 Cubarida3, differing from Cubaris in the form of the cephalon, antennse, 

 maxillipedes, and the first mesosoraatic segment, and in the extension of 

 the uropods beyond the telson. It is of special interest in that it 

 represents a type of Cubarid^e only known as yet from the Western 

 Hemisphere. J- A. T. 



Oral Appendages of Isopoda. — Walter E. Collinge {Journ. 

 Linn. Soc. ZooL, 1918, 34, 65-93, 8 pi.). The first maxilla and the 

 maxillipedes of Idoteidse are minutely described in twenty-four types, e.g.
