 m-anules, space between the granules smooth and shining. Cervical 

 suture indicated by a very distinct smooth sulcus, which is sharp 

 and deep in the longitudinal portions in the middle of the carapace; 

 branchial regions only indistinctly separated from the cardiac. _ 



Front lamellar, very strongly deflexed and its edge divided mto 

 two prominent, roimded lobes, which, when seen m a frcmt view, 

 proiect below the inferior margins of the orbits. 



Antero-lateral margin thin and divided by deep rounded sinuses 

 into four slightly upturned lobes or teeth, of which the anterior, 

 the hepatic, and the^pjbnanchial are broad, andjn^^ 



"T^J^^un^i^^t'lT impossible to'glvo illustrations of this and several «ther species^ 

 the tvpes of which are said to l.e in the Peabody Museum, as a diUgent search in 1916-
