drawn by that author are to be maintained; for in the struc- 
ture of the first pair of feet it completely agrees with some 
genera of Harpacticina, 1. e. Harpacticus M. Epbw. and 
Thalestris CzAvs, and evidently differs from Anmeirina, while 
in the development of the mandible palp and of the secondary 
branch of the posterior antenn&e, itresembles Ameirina much 
more than Harpacticina. "These organs are namely in Amei- 
rina much less developed than in Harpacticina and thus more 
like their rudimentary state in Balenophilus. By its two 
distinet ovisacs it resembles again the genus Diosaccus 
BozrcK. Consequently Balcenophilus seems to constitute a 
remarkable uniting link between the above-named two sub- 
families by presenting characters belonging to both, and 
these characters still more strongly marked even than in their 
typical genera. 
According to the limitation, given by G. BrADY”) 
to the subfamilies and genera of Harpacticida, Balenoplhilus 
may belong to Harpacticina and come nearest to the genus 
Thalestris Ciravs. But from” this genus it differs widely by 
having the mandible palp rudimentary and the maxillary palp 
simple, unbranched. 
One species only being known, the following description 
will cemprise the generic as well as the specific characters. 
Balzenophilus unisetus nov. spec. 
A. Adult form. 
Description: Body (P1. I. Fig. 1—3.) elongated, slightly 
higher than broad, attenuated behind; last segment of the 
abdomen half as broad as the first large part of the body. 
This part provided with a distinct, but obtuse rostrum, and 
being in the male about 0,25, in the female 0,29, of the whole 
length of the body. The four posterior thoracic segments 
free as usual; abdomen in the male composed of five, in the 
female of four free segments, exclusive of the furca. The first 
and second abdominal segments of the female are namely
