upon cases only*. 
(ii.) Fixed cases, probably constructed by the larve of some 
unknown genus and species of Rhyacophilidee, which should be 
of about the size of some of the smaller European species of 
Rhyacothila. The pupais enveloped in a special cocoon, as is 
usual in the family, and does not agree with the genus Rhyacophila 
either in spurs.or palpi. P4Azlanisus having been removed from 
the family, the latter is now without any described representative 
in New Zealand. Oftwo cases one is wholly composed of stony 
(? granitic) fragments; the other partially of similar fragments, 
partially of shells (of two or three species), and partially of the 
cases of the Helicopsyche referred to above. 
SCIENCE-TEACHING IN OUR SECONDARY 
POCEOOLS, “WITH ESPECIAL.” REFERENCE)-FO

DUNEDIN HIGH SCHOOLS.

_ In view of the approaching annual meeting of the Senate of 
the New Zealand University, it is perhaps desirable to take into 
consideration the position occupied by science-teaching in our 
secondary schools, the suitability of the various subjects taught, 
and the nature and amount of encouragement which it receives 
at the hands of the University authorities. Hitherto, those who 
are responsible for this part of our school instruction, have not 
made their voices heard in any discussions which have been 
raised on the subject, and it is with the object of presenting the 
aspect of the question from a teacher’s point of view, that I am 
tempted to advance my opinions in these columns. Limited 
space must be my excuse for treating the question briefly. 
It has been a matter of considerable difficulty to obtain infor- 
mation as to the teaching of science in our secondary schools, 
and my attempts in this direction have not met with unqualified 
success. It is evident, however, that most of the subjects in- 
cluded under the head of science are still treated with a con- 
siderable amount of suspicion by a certain section of the teach- 
ing community, In some cases it is only owing to the pressure 
of outside opinion that they find a place in our curriculum. This 
is most frequently shown by the fact that, with one or two ex- 
* Helicopsyche-cases from New Zealand have long been in the British Museum, 
and have several times been alluded to by me in various published notes.
