by J. Inglis “On a New Species of Diatom,” by J. Inglis. Nitzchia novœ-zealandia. Frustule.—Front view linear, narrowing at the truncated extremities, opposite side of each end obliquely sloping. Valve.—Linear on side view and sigmoid, attenuated towards the extremeties and rounded at the ends. One row of puncta round the margin of the valve. Puncta.—There are twenty-four puncta or beads to one thousand of an inch. I have been unable to make out any striæ or keel under “Becks” one-tenth immersion. The valves of Nitzchia novœ-zealandia resemble Homococladia sigmoidea, but the latter is frondose, and the frustules are sigmoidal on the front view, while the former is free and sigmoidal on the side view. I found this Diatom in quantities, during the months of April and May, in a spring at Nga Pari, on the side of the North Moeraki Downs, facing the River Ashley. I am indebted to Professor Hutton for the verification of this description.
