 anteriorly broadly rounded. Pleonites 2—4, posterolateral margins tubercu- 

 late, middorsal posterior margin excavate with strong middorsal tubercle;

 Figure 74E,F 



DIAGNOSIS 6 9.9 mm, 9 12.0 mm. Eyes well separated. Frontal lamina 

 about twice longer than wide, posteriorly parallel sided, widening anteriorly 

 to broadly rounded apex. Subadult 6 cephalon unornamented except for 

 pair of very low tubercles mesial to eyes. Posterior margins of pleonites 3—5 

 very faintly tuberculate. Pleotelson with submedian pair of low tubercles 

 basally; lacking lateral incisions; apex rounded.

Excorallana fissicauda (Hansen, 1890) 



DIAGNOSIS 1 1 mm. Cephalon unornamented. Eyes contiguous. Frontal 

 lamina unknown. Pleonite 5 with three strong mesial, and several smaller 

 lateral tubercles on posterior margin. Pleotelson with two strong submedian 

 basal tubercles; lateral incision lacking; posterior margin with deep open 

 incision. 



RECORDS St. Thomas, U.S. Virgin Islands. 



REMARKS This species was described from a single specimen, and has not 

 been recorded since. After examining the holotype, Paul Delaney (in litt.) 

 suspects that the terminal incision of the pleotelson may be the result of an 

 injury.
