Ohs. — Malletia elongata has been fully described elsewhere, and 
reasons given for adopting the name. Three imperfect specimens are present 
in local collections of N. S. AVales fossils. One is in the Macleay Museum, 
consisting of the united valves, exhibiting the elongate and somewhat 
upturned posterior ends, the ligament, and fragments of the external shell 
of a deep brown-red eolour. 
Tlie other two examples, even in a loss perfect state of preservation, 
are in the Mining and Geological ALuseum. One is an internal cast of 
portions of the united valves, and the other part of a left valve, with pieces 
of the test remaining.
