DESCRIPTION OF GEXERA AND SPECIES. 



Order PODOPHTIIALMIA . 



Sub-Order SCHIZOPOD A . 



Family LOPHOGASTRID.E. 



Genus TEALLIOGARIS gen. nov. 



Generic Characters. — Body moderately long and slightly applanated. Integuments 

 generally firm and chitinous and only slightly pitted or grained with a slight wrinkling. 

 Carapace large, nearty half the length of the body, and only loosely covering the seven 

 trunk segments, and externally more or less provided with longitudinal keels. Rostrum 

 spear-shaped, three-edged, and denticulated. Hinder part of carapace never produced 

 into backwardly-directed spines. Caudal segments moderately wide with moderately 

 large single lobed epimera. Eye well developed, large, and with papilla issuing from 

 the pedicle. Antenuular peduncle moderately long and slender, the ilagella being short 

 and of nearly equal length. Antennal scale caridean in construction and the Hagellum 

 very niuch longer and more massive than the outer flagellum of the antennule. First 

 pair of legs much more massive than the succeeding ones, which are slender and nearly 

 uniform. Branchins given off from the bases of all the seven pairs of legs, with lobate 

 sternal branches. Telson large and constricted near tip, with a lobate flattened termina- 

 tion, and set on each side by a small articulated plate-like accessory swimmeret. 

 Uropoda caridean in structure, and not as long as the telson. 



The name of the genus is designed to show regard for my old chiel', the Director 

 of the Geological Survey, I>r. J. J. H. Teall, whose name I have associated with the 

 Greek word for shrimp to distinguish it from the recent genus of sea anemones named 

 J'ealia. 



TeALLIuCAIUS LOUDONEXyiS sp. uov. i'l. I., ligs. 1-7. 



As the collection contains better preserved specimens of this form than of anv 

 other of the genus, it may be as well to describe the species in considerable detail, since
