This circle continues in an irregular single row caudad of the 
caudal sete for the usual distance as mentioned in the general 
description. The anterior concavity of circle is very marked, 
the posterior lips being prominent. The concavity is formed by 
a single row of pores for the entire distance. 
Citri Risso—(Fig. 4). The cephalic, median, and caudal pairs 
of sete are equidistant from each other. The outer circle is * 
limited cephalad by the anterior pair of sete. Caudad of each 
posterior sete is a single pore belonging to the outer circle of 
pores. Between the caudal and median sete this row is irreg- 
ularly double for some distance. The anterior concavity of the 
circle is not so marked as in the preceding species. The anal 
orifice is narrower but of the same length as in the preceding 
species. 
Crawii Coq.—(Fig. 3). The relative distance of the pairs of 
sete from each other was apparently not constant. Good 
mounts of this species were difficult to make because of the 
prominence of the anal lobes. The outer circle is single for the 
entire distance. In the inner circle the arrangement of the 
denticulate pores varies slightly. This cirele continues caudad 
of the posterior sete, in a regular single row for the usual dis- 
tance. The anterior concavity is not so marked as in either of the 
preceding species. 
Obscurus Essig—(Fig. 2). The caudal pair of sete are 
nearer the median pair than is the cephalic pair. The outer circle 
of pores is single and is limited by the caudal and cephalic sete. 
It is single for the entire distance except for a single pore just 
caudad of the median sete. In the inner circle at the caudal sete 
there are several denticulate pores, the cephalic one indenting 
the membrane of the orifice. Caudad of the posterior sete the 
circle extends in an irregular double row for the usual distance. 
The anterior concavity is not marked, the concavity being par- 
tially filled by pores which form an irregular double row between 
the cephalic sete. 
Agrifoliae Essig—(Fig. 1). The anal ring is considerably 
larger than those of the preceding species. The cephalic pair
