370 DORIDIDA. 
Body depressed, or subconvex ; integument spiculose ; mantle 
often tuberculate, covering the head and the foot; branchiz 
plumose or-ramose, united at the base, and retractile with the 
anus into a common pallial cavity ; mouth inferior, with two dis- 
tinct oral tentacles (rarely absent); odontophore broad, with 
numerous spines in each transverse row. Bergh has proposed 
the name ARcHIDORIS for the thus restricted typical group. 
ANGASIELLA, Crosse, 1864. 
Distr.— A. Hdwardsi, Angas. Australia. 
Body elongate, rounded in front, attenuated and produced 
into a point behind; mantle everywhere covering the head and 
foot; dorsal tentacles 2; subclavate; branchiz plumose, few, and 
placed before the anus, a little behind the middle of the back. 
As M. Crosse has told us nothing about the retractility of the 
branchize or the condition of the oral tentacles, odontophore, 
etc., we cannot be certain of the position of this group. 
Kentroporis, Bergh, 1876. 
Distr.—3 sp. Australasia. K. rubescens, Bergh. 
Mantle broad, soft, with the upper side everywhere minutely 
granular; rhinophores retractile; tentacles conical; branchize

emarginated ; rounded behind; no buccal armature ; no median

Body elongate, subquadrate; mantle narrow, covering. the 
head but not the extremities of the foot; generally smooth and

spines, one in front of the other, the posterior one bearing den- 
ticulations, no central plate; a buccal collar, formed of two 
broad plates, bearing close minute bifid: spines. 
APHELODORIS, Bergh. Somewhat like Chromodoris, but.mantle 
and foot narrow; tentacles truncate, canaliculate ; ‘gills retractile, 
consisting of five tripinnate leaves; labial disk unarmed. Radula
