the posterior. In cirrus I it is half as long, the numbers of seg¬ 
ments being 11 and 15; in cirrus II the anterior ramus measures 
about 3 /5 of the posterior; the numbers of segments are 10 and 
16. In cirrus III the rami are subequal with 16 and 21 segments. 
The caudal appendages are siender and about half as long 
as cirrus VI with 19 segments. 
The species comes near to Verruca Koehleri Gru vel (1907), 
and Verruca intexta Pilsbry (1912). 
From the first named species the 
sculpture differs very mueh, although 
the number of articular ridges of 
the tergum and scutum generally 
coincide. The prominent ridges of 
the movable tergum between the 
diagonal crista and the carinal margin, 
and the rather prominent apex of 
the tergum are especially characteristic of the present species, 
whereas they are lacking in Verruca Koehleri. Also the rostrum is 
mueh larger in Verruca Kriigeri. 
The sculpture of the tergum in Verruca intexta seems to coin¬ 
cide with Verruca Koehleri, although the ribs are even less num- 
erous. Moreover the words of Pilsbry (1912): „Carina and 
rostrum interlocking with numerous teeth“, and „beak of carina 
somewhat produced “ do not agree with the features of Verruca 
Kriigeri. In its number of articular ribs this species holds an 
intermediate position between Verruca intexta and Verruca Koehleri 
although in most cases it agrees with the latter. 
The specimens from Tueuran must, therefore, be taken as re¬ 
presentatives of a new species. I have named it after the cirriped 
investigator Paul Kr uger, who has greatly contributed to our know- 
ledge of the group. 
Owing to its prominent rostrum, which emancipates itself horn- 
like from the other plates of the wall, the present species together 
with Verruca nexa Darwin, Verruca Koehleri Gruvel, and Verruca 
intexta Pilsbry according to Pilsbry (1916) belong to the group 
of Verruca nexa under his section Verruca. I should prefer to se¬ 
parate the nexa-g roup of this section as a section of its own, and
