Paracerceis glynni 221 



pleotelson inflated, faintly tripartite, with strong median conical tubercle; 

 notch in posterior margin shallow, with low median tooth and tiny lateral 

 denticles; posterolateral margins finely dentate. Uropodal exopod cylindri- 

 cal, distally denticulate, six to seven times longer than basal width. 9 : Per- 

 eon and pleon much as in 6, but pleotelsonic notch shallower and 

 posterolateral margins not denticulate. Uropodal rami subequal, lamellar, 

 exopod with distolateral angle acute.

DIAGNOSIS 6 4.0 mm, $ 3.1 mm. S: Posterior three pereonites and 

 pleonites each with irregular row of small tubercles near posterior margin, 

 densely setulose tubercles becoming spinose more posteriorly. Pleotelson 

 with strong median conical tooth in anterior half, flanked by convex spinose 

 mound. Pleotelsonic notch deep, with elongate median basal tooth bearing 

 strong acute tooth at its base. Lobes of posterior pleotelsonic margin broad, 

 flattened, margins denticulate. Uropodal exopod tuberculate, tapering, api- 

 cally acute. 9: Integument much less tuberculate-spinose than in 6 . Imma- 

 ture 9, posterior margin of pleotelson with faintly rounded median lobe. In 

 mature 9 , posterior margin distinctly trilobed. Uropodal rami subequal, 

 lamellar, distally rounded, with tiny distolateral spine on exopod.

DIAGNOSIS 6 6.4 mm, 9 5.2 mm. S: Integument becoming strongly setose 

 and tuberculate posteriorly from about pereonite 5. Posterior margin of inf- 

 lated anterior area of pleotelson bearing strong median conical tubercle and 

 smaller acute lateral tubercle, with low swelling beneath each lateral tuber- 

 cle. Posterior notch deep, narrow, with small basal median tooth, lobes form- 

 ing notch tricuspid, outer cusps recurved dorsally. Uropodal exopod fairly 

 straight, cylindrical, apically acute. 9 : Body far less setose and tuberculate 

 than 6 . Pleotelson with strongly inflated anterior area having very faint mid- 

 dorsal tubercle; notch well marked, formed by triangular lobes of
