Minyako, Rikiizen, 1 male. 



Length 51.(3 mm., length of ro.strum J>.5 mm., width 78. !» nnn. ; 

 length measured from outer ang-le of orbit backward 45 mnL 



Carapace transversely ol)long, without lateral angles, covered with 

 minute vesicular s'.^tte springing' from minute punct^e, and also with 



larger puncta:^. There is a 

 i" prominent protuberance on 



the cardiac region, and one 

 on either side of it on the 

 branchial region, the three 

 forming' a transverse series 

 and springing from a com- 

 mon l^ase. A similar prom- 

 inence occupies the gastric 

 region, and through it a 

 median ridge runs on to the 

 distal half of the rostrum. 

 The anterior half of each 

 lateral expansion is occu- 

 pied l)y a low prominence Avhich is tuberculated. The right expansion 

 is a little larger than the left. The margin of the carapace is furnished 

 with small blunt teeth or tid)ercles at irregular and remote intervals; 

 these number about 34, the largest ones being at the outer angle of the 

 orbit. The rostrum is moderately detlexed, projects well beyond the 

 anterior margin of the carapace, is nearly as long as its width at base,
