representatives of the various institutions and societies with which he

" For a period of nearly thirty-five years then Professor Stephens 

 lived in our midst, labouring uninterruptedly in the cause of higher 

 education, yet finding time and inclination to give the colony at large 

 the benefit of his extensive knowledge and experience by his connec- 

 tion with several of our important public institutions such as the 

 Public Library of which he was Chairman of Trustees, and the 

 Australian Museum of which he was a member of the Board. For a 

 time also he was President of the Sydney Branch of the Geographical 

 Society of Australia. In his favourite pursuit of Natural Science he 

 was actively identified firstly with our fore-runner, the Entomological 

 Society of New South Wales, and afterwards with this Society dating 

 from its inception, having been a member of Council during the years 

 1875 and 1876, ^President in 1877 and 1878, Vice-President in 1879 

 and 1880, Co-Honorary Secretary in 1881-84, and again President 

 from 1885 to the close of his life in November 1890." 



List of Fishes of N.Z. — Under date, Christchurch, 15th April, 

 1891, Professor Hutton writes : — "In my List of the Fishes of New 

 Zealand published in the ' Transactions N.Z. Institute,' vol. xxii, p. 

 275, I have omitted the following species.

Crustacea raised from dried New Zealand mud. — At the 

 request of Professor G-. O Sars, of Christiania, Norway, I sent that 

 gentleman during last summer, some samples of dried mud taken 

 from fresh-water ponds or lagoons. One lot was collected by Mr. 

 Chilton at Eyretown, Canterbury, from a locality which yields 

 abundance of Boechia triarticulata, as well as other forms of minute 

 Crustacea. Two other lots were taken from dried-up lagoons in the 

 Taieri Plain. The materials were sent by post in April last,. and on 

 receipt were at once placed in suitable aquaria. From letters 

 received since it is interesting to learn that the results of the 

 experiment have proved very satisfactory. In nearly all the aquaria 

 prepared with mud from Eyretown Daphriia similis, (mihi), has been 

 successfully hatched, and has increased in a very remarkable manner. 

 Along with this numerous specimens of a Cypris aj>peared. This 

 species Prof. Sars takes to be my Cypris ciliata, and he Avas at 

 first inclined to consider it as Ilerpetocypris stanleyana, (King), 

 which he has raised from dried Australian (Queensland) mud. 

 But another form raised from the Taieri mud agrees much more 

 closely with King's species, as subsequently described by Mr. 

 Brady. The Eyretown mud also yielded specimens of a very distinct 

 and beautiful species of Diaptomus, which is probably identical with 

 my Boeckia triarticulata. Prof. Sars goes on to say : — "The parcel of 

 mud from the neighbourhood of Dunedin has, besides the above- 

 mentioned Cypris, yielded numerous specimens of a Simocephalus, 

 which I supose to be your Daphnia obtusata, a species of Ceriodaphnia, 

 a, small Chydorus (probably your C. minutus), and four additional 

 species of Ostracoda, viz., two species of Herpeiocypris (one of which 

 has also been raised from Australian mud and described as H viridula, 

 Brady), one species of Cypridopsis, and one of Notodromas (of which
