 proximately 48 ,u long nil id a m, new species, p. 139. 



Marginal quinquelocular pores much more numerous than 

 above, in a complete row terminating nt or near the pos- 

 terior 8-shaped pores; apical setae approximately 56 M long

Dorsum with or witboul 8 shaped pores, but oot thickly strewn 

 with pores measuring 12 13 ,« Long and 8 '•• wide; if some 

 dorsal B-shaped pores approximate this size, then there are 

 Less than 40 quinquelocular pores in each spiracular hand 30

in lateral and submarginal areas: marginal quinquelocular 

 pores present around most of margin; multilocular pores, 

 totaling 26-33, in 4 complete and 2 or 3 interrupted rows

a single row near posterior end of body and continuous

 sent between apical setae 34
