TUN1CATA. 
Systematic.

ASOIDIACUA. 
ASCIDIiE SIMPLICES. 
Earn. i. Clavelinidje. 
A new variety of Clcivelina lepadiformis , cinnamomea n. var., is described 
by Herdman (5, p. 296), from the Isle of Man. 
Fam. ii. AsciDiiDiE. 
Roule (19) divides this family ( PhcillusiacUes ) into 2 subfamilies : the 
Cionidees and the Phallusidees. He revises the species of the coast of 
Provence, and describes as new : — Pleurociona y n. subg., of Ciona (p. 239), 
P. edwardsi, n. sp., Houle, (19) p. 240. 
Ciona aspcra y n. sp., Ilordman, (4) p. 416. 
Ascidia elongata , n. sp., Roule, (19) p. 251 ; A. fallaxy n. sp., Drasclio, 
(2) p.102. 
Fam. hi. Cynthiidje. 
Culeolus ioillemoe8i y n. sp., Herdman, (4) p. 403. 
Balhyoncus discoideus and B. minutus , n. spp., id. t. c. pp. 407 & 409. 
Polycarpa bassi and P. aspera , n. spp., id. t. c. pp. 413 & 415 ; J*. 
monensis , n. sp., op. cit. (5) p. 305. 
Fam. iv. Molgulidjj. 
Eugyra symmetra , n. sp., Drasche, (2) p. 103. 
Molgula carpenteri, n. sp., Herdman (4) p. 401. 
ASCIDLE COMPOSITE. 
The position and the classification of this group are fully discussed by 
Herdman (4), and 88 new species, 10 new genera, and 2 new families are 
described. The Compound Ascidians are defined as “fixed Ascidians, 
which reproduce by gemmation, so as to form colonies in which the 
Ascidiozooids are imbedded in a common test'’ (p. 28). 
Fam. i. BotrylliDjE. 
Botrylloides tyreurn (= B. pinpureum, Herd., not v. Drasche), B. per- 
8picunm (and rubicundum n. var.), B. nigrum and B. fulgurale, n. spp., 
Herdman, (4) pp. 41, 45, 50, & 52.
