MILLIPEDS OF PANAMA—LOOMIS Ly 
spots; sides of several specimens darkened somewhat, others entirely 
light. 
Ocelli dark, in three rows starting nearest antenna, 3-6—7-or 3- 
i-or 4-758. 
Segment 1 rather broadly rounded on each side, a raised rim on the 
front margin from behind eye to the lateral limit, above which, from 
posterior margin, a short stria extends forward and upward; above 
this a stronger stria nearly parallel to the anterior rim and, in some 
specimens, almost as long; a very short stria occasionally present 
above the long one. 
Ensuing segments flat with only the faintest indication of a trans- 
verse constriction, the back margin thin and not noticeably raised 
above the next segment; surface of segments smooth and shining 
throughout, there being no lateral striations except on segments 
2 to 6 or 7 after which there are only one or two short ones ventrally 
adjacent to the sterna. In several specimens lighter lines in the 
body wall indicate the divisions between forebelt, midbelt, hindbelt, 
and the longitudinal junction of dorsum and venter; pores large and 
located at intersection of lateral and second transverse line. 
Last segment with apex short, thick, rounded and _ projecting 
slightly beyond anal valves in lateral view. 
Gonopods as shown in figure 7h, the mesal face of the lower half 
of each with many tiny, short, conic tubercles. Segment 7 of the 
male not raised behind gonopods.
