Carapace slightly to moderately convex, front wide. Rostrum 

 moderately long, spinelike, triangular in cross section, exceeding 

 eyestalks by about three times the length of the cornea ; rostral carina 

 sharply ridged, furnished with a double row of light corneous scales 

 closely juxtaposed and more or less alternating up to a little anterior 

 to the level of the posterior margin of the orbits, where the scales 

 form a single, closely set row of scales which extends to the anterior 

 extremity of the rostrum. 



Figure 44. — Aegla sanlorenzo, new species, male holotype: a, Dorsal view; b, lateral view of 

 anterior portion; c, sternum of third and fourth thoracic somites; d, inner ventral margin 

 of ischium of left cheliped; e, lateral view of second abdominal epimeron. a, b, natural 

 size; c-e, twice natural size. 



Epigastric prominences low, with few small beadlike scales on sum- 

 mit; anterior margins of protogastric lobes forming an acute angle 

 outlined by a closely-set row of light-colored scales; similar scales 

 scattered elsewhere over carapace. Areola moderately wide, fairly 

 long. 



Orbits only moderately wide, moderately deep, separated from the 

 fairly wide extraorbital sinus by a well-developed orbital spine; ex- 

 traorbital sinus about one-half the width of orbital. 



Anterolateral spine long and slender, sharply spinif orm, exceeding 

 the cornea. First hepatic lobe sharply spined anteriorly, spine end- 

 ing in a slender corneous tip and appreciably exserted; second and 

 third hepatic lobes set off by not very prominent, rather weak notches, 

 margins corneous-granulated or scaled.
