Northern Island: Bay of Islands, on the ground, J. B. H. ; Auckland, Knight, Sin- 
clair (a form with no teeth). Mr. Wilson, who has examined the Auckland specimens 
very closely, finds no trace of teeth, and suggests that this may be a different species, for 
which he proposes the name Ognostomum patulnm. The specimens are all immature.
