SUMMARY OF CURRENT RESEARCHES RELATING TO 
They are of two kinds, “ champagne-cork-like ” and “ bottle-like,” but 
may be referred to the same type. Their peculiarity is that between 
the chitinous terminal part and the ganglion-cell there is interpolated a 
glandular part. They are in all likelihood olfactory. In a subsequent 
paper f Bertkau notes that Gaubert has recently described the “ bottle- 
shaped ” organs in Galeodes barbarus. 
Pentastomum denticulatum.J — Herr St. v. Eatz found in the liver 
and lungs of a sickly sheep a large number of Pentastoma , which caused 
a considerable destruction of tissue, and gave rise to a catarrhal 
pneumonia. The parasites appeared to be migrating in a centrifugal 
manner. 
€. Crustacea. 
Phylogeny and Classification of Crustacea.§ — Prof. K. Grobben has 
attempted to refer not only the Entomostraca but also the Malacostraca 
to three types of existing Euphyllopoda — BrancMpus, Apus, and 
Estheria. A comparison of the most essential characters of these forms 
shows that the Cladocera and Ostracoda may be referred to stem-forms 
resembling Estheria, the Copepods and Cirripedes may be related to an 
Apus-like stem-form, while the Malacostraca are to be referred to a 
stem-form of which the BrancMpus- type is a remnant.
