One last point which must be discussed is the variation 
in the number of eyes. Agrell, Kseneman, Stach and a num- 
ber of other investigators have accepted the fact that the 
number of eyes in at least some species of Folsomia is 
varible. Gisin in 1946 has stated that this condition has 
not been proven for any species of the genus. Among the 
specimens I have identified as F. penicula are occasional 
specimens with a single pair of eyes, and in one case a speci- 
men lacking eyes entirely. Beyond this, an occasional (2) 
small sample may consist of all one-eye paired forms. In 
all cases, and particularly where the four-eyed and two- 
eyed forms occurred in the same population, a slow, care- 
ful comparison was made between the two-eyed and four- 
eyed forms and not the slightest difference other than the 
eyes could be found. To assume that these represent dif- 
ferent species, particularly where the one-eyed paired 
forms represent two specimens in a sample of thousands, 
is to my view sheer folly. I feel therefore that I can state 
with authority that in the species I call penicula there are 
both two-eyed and four-eyed forms. The two-eyed forms 
are undoubtedly synonymous with those specimens iden- 
tified by Cassagnau as Ksenmani. It is entirely possible 
that these two species are synonyms but before this can be 
ascertained the whole group must be thoroughly reviewed.

The specimens at hand agree very well with the figures 
and descriptions given in Stach. The only notable dif- 
ference was the absence of an inner tooth on the unguis. 
In this respect the present specimens are similar to Bag- 
nail’s distincta , but I agree with Stach that there is 
insuffieent grounds for separating this species at the 
present time. The evidence of Delamare (1950 )and this 
material point to a locally variable widespread form. The
