This beautiful species grows to be nearly the largest of recent 

 brachiopods and in form one of the most regular. In color it varies 

 from a suffused rose color, to the variety miniata Gould, which is 

 yellowish, pamted with radial streaks of red. The oval form which 

 Davidson described as T. boucJiardi (var. 6.) occurs rarely among the 

 specimens I have seen. The shell figured in the atlas to the voyage 

 of La Perouse by Lamanon, and which was called lamanoni by 

 Schrenck in 1867, is not perhaps identifiable with anything, certainly 

 not with the present species whose arched back could hardly have 

 been ignored by the draughtsman, as it is characteristic of even the 

 youngest specimens, and is responsible for the deep median sulcus 

 of the pedicel valve. The foramen is large and the rugose deltidia 

 not coalescent, sometimes meeting, and sometimes the gap between 

 them is filled by an irregular calcareous plug. The teeth are strong, 

 the props reduced to a pinpoint dimple in a mass of callus in the 

 adults. There is a low ridge bifurcate anteriorly between the mus-
