of the free portion of the rostrum apparently becoming a some- 

 what broken or irregular single line of scales ; the more prominently 

 raised portion of the carina extends backward about to the level 

 of the epigastric prominences of the carapace, posterior to these the 

 carina is less prominently marked to between the anterior margins of 

 the protogastric lobes where the carina fades out. Epigastric prom- 

 inences blunt-nodular, anterior margins of protogastric lobes scarcely 

 or poorly marked, obsolescent and not scaled. Areola short and wide, 

 squat looking. 



Orbits of good size, fairly deep, typically without an orbital spine, 

 and usually with scarcely any or only (rarely) a very slight inter- 

 ruption or offset in the outward sweep of the orbital margin at the 

 point where it passes over into the inner margin or slope of the antero- 

 lateral spine of the carapace; in the very largest specimens, such as 

 the type, there is more of an offset than in any other specimens of the 

 species that I have seen ; there may be one or a few tiny spinules along 

 the outermost portion of the orbital margin, but in no sense is any 

 of them of sufficient consequence to be considered as representing 

 an orbital spine. 



Anterolateral spine of good size, anterior extremity reaching nearly 

 or about to the level of the middle of the cornea ; the dorsal surface 

 of the anterolateral lobes is much flattened, almost or slightly exca- 

 vate, giving the impression that the anterolateral spines are inclined 

 upward to a greater extent than in any other species of Aegla. An- 

 terolateral angle of first hepatic lobe slightly scabrous and more or 

 less rounded off; just within and below the angle of the right first 

 hepatic lobe of the type is a low projection or tubercle, which is 

 occasionally present in other specimens on one or the other side or 

 sometimes on both sides ; second and third hepatic lobes slightly indi- 

 cated, in some specimens scarcely so. 



The larger hand is of good size, moderately inflated or swollen; 

 on the upper surface of either palm there is a faint, obsolescent, yet 

 plainly discernible, low, obliquely longitudinal, narrow swelling run- 

 ning from near the outer posterolateral angle of the palm to the pos- 

 terior margin of the sinus between the fingers; this ridge is scabrous 

 like the rest of the hand, and is more evident in the smaller specimens 

 than in the very largest ones. On the outer margin of the movable 

 finger of either hand, near its posterior end, there is a well-defined 

 lobe or projection, anteriorly angled and carrying there a small spine 

 or spinule; lobe otherwise scabrous, or very small-spinulose. What 

 there is of a palmar crest (on inner margin of palm) is broadly 

 and shallowly serrate, fairly thin-edged and furnished with a scatter- 

 ing of small spinules; the crest runs back from below the movable
