224 DR. H. WOODWARD ON CRETACEOUS PODOPHTHALMATA [May 1 896, 



II. BRACHYURA— ANOMALA. 

 Family Homolidae. 



Genus Homolopsis, Bell. 



Carapace longer than broad, quadrilateral ; regions of carapace 

 very distinct ; branchial region large, triangular ; orbits close 

 together, frontal region rather produced ; front subrotund. 



2. Homolopsis Richardsoni, sp. no v. (Fig. 3.) 



This interesting little crab was obtained by Mr. James Richardson 

 in 1872 from Skidegate Inlet, west of Alliford Bay, Queen Charlotte 

 Island, and is preserved in a hard black limestone-nodule containing 

 plant-remains. Portions of the limbs still remain in their normal 

 position, showing that it was entire when originally buried in the 

 matrix. 



Length of carapace 20 millim., greatest breadth 17 millim. ; 

 breadth of posterior border 14 millim. ; breadth across hepatic 

 region 14 millim. 



The carapace is broadly quadrilateral, but pointed in front ; the 

 branchial regions extend to fully one half the length of the 

 carapace ; they are roughly 



triangular in shape, _ and -p- g 



nearly meet on the middle 

 line behind the cardiac re- 

 gion ; cardiac region small, 

 shield-shaped, but elevated ; 

 metagastric region marked 

 by two small prominences ; 

 hepatic regions prominent. 

 Two very distinct and almost \J 

 parallel furrows, the bran- \ ' ^|. 

 chial furrow and cervical \ \ 



or hepatic furrow, diverge 

 from the sides oft he cardiac 

 and metagastric regions 



obliquely forward towards the lateral margins of the carapace.' Two 

 deep submedian furrows mark the frontal portion of the cephalo- 

 thorax, reaching to the rostrum, where they converge on the central 

 line. Two small spines (or other appendages) project (as in the 

 o-enus Latreillia) from the rostrum on either side. 



The hinder border is extremely wide and straight, and suggests 

 the broad margin for the attachment of the tail as in the females of 

 all the Anomala, in which section the abdomen is only partially 

 concealed beneath the cephalothorax. 



The surface of the carapace, which is tumid, is coarsely and 

 irregularly covered with small rounded tubercles, which are larger 

 on the gastric and hepatic regions. 



The walking-legs were evidently long and fairly large, and the 

 chelipeds curved and tuberculated as in Homola.
