THE GENUS ENOPLOCLYTIA IN THE CRETACEOUS 

 ROCKS OF QUEENSLAND. 



By R. Etheridge, Junr., Curator. 



(Plates xxiii. and xxiv.) 



Comparatively few Crustacean remains liave, so far, been 

 found in the Cretaceous of Queensland, or for tlie matter of 

 tliat tlirouc^liout Austi-alia generally. A short note by myself, 

 published in 1892 gives details of all that was known up to 

 that date.i Emphasis is there laid on the occui'fence of both 

 the Macrura and Brachyura. 



The Trustees have, from time to time received from Mr. W. 

 H. Blomfield collections of Queensland Cretaceous fossils 

 collected by him. In a series received some time ago occurred 

 a specimen of great interest being the greater portion of a 

 Macruran carapace apparently referable to Enoplodi/tia, 

 McCoy. 



The specimen consists of the carapace less the rostral por- 

 tions, and all api)endages. It is sharply bent down along the 

 dorsal median line, leaving the lateral portions but very little 

 convex, indeed the entire body may be said to be highly com- 

 pressed ; on the right side the ventral margin is fairly well 

 preserved, but on the left it is wanting. The general outline 

 of this carai)ace is long-oval, and in its present compressed 

 condition rather broadly pod-shaped, the entire surface being 

 highly tuberculate. The posterior margin is only preserved 

 towards its ventral latei-al portions which are rounded. 



The nuchal furrow is deep, wide, devoid of tubercles and 

 faintly signioidal on each half of the shield, cui'ving forwards 

 on approaching the ventro-lateral margins and running 

 parallel to the latter forwards for a short distance. At about 

 the middle of its course there is a short open supplementaiy 

 groove directed forwards. The niesobranchial furrow, like 

 the nuchal, is deep, devoid of tubercles, but not so wide, and 

 is double, one groove behind the other, but close together
