material it is not to be wondered at that many interesting results were 
obtained. 
Twenty-nine new species belonging to ten genera of Limnobinae, and 
twenty-two belonging to five genera of Tipulinae are described ; they 
are all now extinct, and none are identical with any of the few described 
tertiary Tipulidae of Europe ; eight of the fifteen genera of the Florissant 
basin appear to be extinct ; there are no extinct groups higher than 
genera, though some of them are of a somewhat striking character. 
The relative importance of the two sub-families of Tipulidae, though 
differing in Europe and America both in tertiary and recent times, was 
much the same, on each continent, in tertiary times as now ; in the 
relative preponderance of the different tribes of the Limnobinae the 
American tertiary fauna exhibits a somewhat closer agreement with the 
European tertiary than with the existing American fauna. 
No certain indications of a warmer climate, such as is shown by other 
groups, is given by the American tertiary Tipulidae. 
J3. Myriopoda. 
Myriopoda of North America.* — Dr. L. M. Underwood edits the 
already published and the posthumous papers of the late C. H. Bollman ; 
that of the latter which is of greatest interest deals with the classification 
of the Myriopoda. The great differences between the two principal 
orders of the group as generally understood are recognized, and it is 
proposed to call Etymochila the group which contains, as subclasses, the 
Syngnatha and the Hexapoda (Insecta), as it is the only group of 
Arthropods that has a true labium. The name Myriopoda is confined 
to the Diplopoda and Pauropoda ; for the latter subclass the name 
Monopoda is proposed. 
The Diplopoda are divided into two suborders, the Cliilognatha and 
Podochila (Polyxenidae) ; the former break up into three orders : — 
(1) Colobognatha, with the family Polyzoniidae ; (2) Helminthoinorpha, 
with the families Julidae, Craspedosomidae, Callipodidae ; and (3) Onis- 
comorpha for the Glomeridae. 
The Syngnatha | are divided into the Anamorpha and the Epimorpha ; 
the former containing the Lithobiidae, Cermatobiidse, and the Scutigeridae, 
and the latter the Scolopendridae and Geophilidae. For the diagnoses 
reference must be made to the original. 
Structure of Pauropus.J — Herr P. Schmidt gives a preliminary 
report of his investigation of the structure of Pauropus Huxley i Lubb. 
It may be enough at present to note his general conclusions : — 
(1) Pauropus has no primitive characters, less at any rate than the 
Chilopoda ; (2) it is the simplest Myriopod as yet described, but its 
simplicity is secondary and degenerative ; (3) it is most nearly related 
to the Diplopoda, and among these to the Pselaphognatha (Polyxenidse).

Lateral Eyes in Galeodidae.§ — Mr. H. M. Bernard announces the 
discovery of lateral eyes in Galeodidae, a group supposed to be unique
