below the cardinal process to the middle of the valve, ceasing abruptly; 

 there is a deep squarish notch in the posterior edge of the upper limb 

 of the loop, and below this the opening which usually exists in this 

 place is entirely closed by a calcareous plate, while the distal ends of 

 the lower limbs of the loop project as two small unattached points 

 about 2 millimeters long. Height of the shell 18.0; breadth 18.0; 

 diameter 9.5 mm. U. S. Nat. Mus. Cat. 'No. 111059. 



Type locality. — U. S. Bureau of Fisheries station 5172, oS Jolo, 

 Philippines, in 318 fathoms, sand; one specimen and a fragment. 



I have some hesitation in referring this species to Camjxiges on 

 account of the props in the pedicel valve (which Hedley does not 

 refer to and are presumably absent in the C. furcifera), the divided 

 cardinal plate and the projecting spurs of the lower part of the loop. 

 Otherwise the resemblance is close. The closed aperture I presume 

 is due to coalescence of spicules, but this demands more material to 

 determme. Meanwhile attention may be called to its peculiarities 

 by regarding it as a section of the genus. The specimen described 

 was dead when dredged but retained the loop unmjured.

Magasella Dall, Amer. Joitrn. Conch., vol. 6, p. 134, 1870. 



Type. — Terelraiula fiexuosa King. Magellan Straits. 



The type upon which this group was originally based was supposed 

 to be Terehratella evansi Davidson, 1852. A recent study of the 

 material upon which my original diagnosis was based shows that 

 the specimens really belong to the T.flexuosa of King, 1831. 



The confusion which reigned in the period just previous to and 

 somewhat after the epoch-making discovery of Friele, in regard to the 

 changes which take place in the form of the loop, during the develop- 

 ment of the Terebratelloid brachiopods, was very great and affected 

 all our synonymy.
