Vs, 7 . Thus the papillæ in the Danish specimen seem to be in- 
considerably smaller. 
As to the question of the specific value of this form I shall 
not venture to express any opinion on account of the lack of suf¬ 
ficient material; as is known Brakenhoff has established it as 
a new species while Micoletzky considers it as a mere variety 
of T. gracilis. 
Cephalobus ciliatus (v. Linst.) d. M. 
This species was found in material for which I am indebted 
to Stud. mag. Lieberkind. It originates from a strand-meadow 
on the Island of Mors in the Limfjord. The locality is near the 
water and in winter and early spring temporarily overflowed. Ma¬ 
ture specimens were found in May. 
Dovylaimus Leuckavti Btsli. 
This species which hitherto was not observed in Denmark has 
proved to be rather common on roots of plants in Charlottenlund 
forest, near Copenhagen. It was found in moist and fat mould.
