NOTES ON RETICULAKIAN RHIZOPODA. 271 



Frondicularia compta, n. sp, PI. VIII, fig. 6. 



Characters. — Test long, spathulate; truncate or emarginate 

 at the base, obtuse-angular at the apex; margin square, 

 somewhat lobulate. Early segments larger than the later 

 ones, sutural lines limbate. Surface otherwise smooth. 

 Length ~ inch (TO millim.). 



A very beautiful little shell, with just sufficient irregularity 

 in conformation to make it difficult alike to describe in well- 

 defined terms or to reconcile with previously recorded species. 

 The earlier portion of the test is built on a bolder, larger 

 plan "than the latter part, and the septal lines are thickened 

 and raised. The later segments are narrower and smaller, 

 and the sutures, though still limbate, are not so prominent. 

 The peripheral margin is nearly square. 



The figured specimen was found at Station 163, Bass 

 Strait, 38 fathoms.

Flabellina cuneata {i'07i Miinster). PI. VIII, fig. 7. 



Frondicularia cuneata, Von Miinster,^ 1838. ' Neues Jahrbuch fiir Min.,' 

 1838, p. 383, pi. 3, fig. 10. 



Notwithstanding the more regular contour of the recent 

 specimen and its somewhat larger number of segments, 

 there is no real impropriety in identifying it with 

 Von Miinster's species; less impropriety, at any rate, than 

 adding a fresh name to an already over-named genus, on 

 insufficient grounds. Our recent shell, like Von Miinster's 

 figure, is long, narrow, and tapering to a point at the base. 

 The early segments are set obliquely and rather irregularly; 

 there is no external limbation or thickening of the sutural 

 lines, and the surface is traversed by delicate, nearly parallel, 

 longitudinal striae or riblets. The length of the specimen, 

 which is not quite perfect, is about ijV inch (1*0 millim.). 



Habitat. — off the Ki Islands, 129 fathoms. 



Flabellina foliacea, n. sp. Pi. VIII, figs. 8 — 10. 



Characters. — Test depressed, complanate; peripheral 

 contour variable, often more or less carinate. Chambers 

 slightly inflated. Spiral segments irregular; equitanfr
