55. Cythere fungoides (G. S. Brady), (PI. XIX. fig. 7, a-d). 



Cythereis fuiKjoides, Brady, Trans. Zool. Soc. (1865), vol. v. p. 385, pi. Ixi. fig. 7, a-d. 



Shell very tumid ; seen from the side, subtrapezoidal, nearly equal in height through- 

 out, height equal to more than half the length, the entire circumference irregularly 

 indented and spinous ; extremities nearly ecjual, obliquely subtruncate, scarcely rounded ; 

 dorsal margin sloping slightly backwards, irregularly indented, almost laciniated ; ventral 

 irregular, slightly convex ; seen from above, the outline is irregular and subhexagonal, 

 greatest width behind the middle, and equal to two-thirds of the length ; lateral margins 

 converging slightly towards the front and much more abruptly behind ; extremities broad 

 and truncated ; the whole outline, except the extreme front, much jagged and dentated ; 

 end view pentagonal ; height scarcely as great as the width. The surface of the shell is 

 rough, especially on the dorsal aspect, with irregular crests and tubercles. Length, l-38tli 

 of an inch ("66 mm.). 



Dredged ofl' Booby Island (Station 187) in 6 to 8 fathoms; ofi' Bermudas, 435 

 fathoms (Station 33) ; and in lat. 9° 59' S., long. 137° 50' E., 28 fathoms (Station 189). 



The type specimen is Australian, and is even more laciniated in its sculpture than that 

 here figured.

56. Cythere imtagoniensis, n. ,sp. (PL XXIII. fig. 3, a-d). 



Shell oblong, compressed ; seen from the side, the greatest height is situated in front 

 of the middle, and is equal to more than half, the length ; anterior extremity broad, weU 

 rounded, and divided into a series of broad blunt teeth, posterior narrow, scarcely rounded, 

 armed with five or six short blunt teeth below the middle ; the dorsal margin is gibbous 

 in front, thence sloping steeply backwards in an irregularly sinuous line ; ventral margin 

 straight ; seen from above, the outline is comj)ressed, subhastate, more than twice as 

 long as broad, widest behind the middle, from which point the sides converge very 

 gradually towards the front, and sink at an abrupt angle behind, thus forming a deej) 

 excavation ; the extremities broad and truncated, with dentated margins ; end view 

 subtriangular, with sinuous sides and broadly rounded apex, the base-line broadly keeled. 

 Surface of the shell very irregularly nodulated. Length, l-40th of an inch ('65 mm.). 



Several specimens were dredged off" the coast of Patagonia in lat. 50° 10' S., long. 

 74' 42' W., 175 fathoms.
