A NEW PLEUROSIGMA.—It may interest microscopists to 
learn that Pleurosigma has at last been discovered in New 
Zealand. Mr. Inglis, of Christchurch, a few weeks ago, dis- 
covered this diatom, which he takes to be a new species, and 
names “ Pleurosigma Crookii,” in a drain at New Brighton. He 
has subsequently found the same species inland at Weka Pass, 
North Canterbury.

Its operculum and radula prove that it belongs to the Tvochide.

N. Z. SYSTEMATISTS.—We have much pleasure in adding to 
the list of names already given those of Mr. T. W. Kirk, of the 
Colonial Museum, Wellington, and Mr. E. Meyrick. The 
former gentleman is already well known for his researches on 
Crustacea, Mollusca, and Annelida, and is desirous of obtaining 
specimens belonging to these groups. 
Mr. Meyrick has recently come to this Colony, having 
received an appointment in Christ College, Christchurch, and is 
engaged working up the Micro-Lepidoptera (Pyrales, Tortrices,
