lidcti ; 12, Amphictenidui ; 13, Hermellidai ; 14, Serpulidoi: and the Nereidce 
into — 1, Aphroditidce ] 2, Pahnyridce-, 3, Amphinomidce 4, EunicMca \

Balanoglossus and Polygordius are placed as appendages to the Annelides. 
The Ciliata are divided into the Bryozoa and Rotatoria, and the latter 
into six families — 1, Flosculariidm ; 2, Philodinidoo ; 3, Brachionidce •, 4, 
Ilydatinidoi \ b, Asj)lanchnidco\ 3, Alhertidce. 
Lankester (3) thus divides the Platyhelmia : —

The Gephyrea into four classes — Bchiuridw, Priaptdidce, Sipunciclidce, 
and Phoronidce. 
The Nematoidea are divided into — 1, Ascaridai] 2, StrongylidcG 3, 
Trichinidoi ; 4, FUariidai ; 5, Mermilhidoi ; G, Gordiidoi ; 7, Angtiillididai ; 
8, FnopUdai ; 9, Chwtosomldiv. 
The Platyhelmia, Gephyrea, Enter opneiista, Nematoidea, Chcetognatha, 
and Appendiculata (in which are included the Gnathopoda) are regarded 
as separate “ phyla.” The Solenogastres form grade A (Lipoglossa), or 
Scolecomorpha, of the first branch {Encephala) of the Mollusca. 
The Appendicidata are divided into — 
Branch A. Chcctopoda. 
I. Oligochoita . . 1. Naidina. 
2. Scenurina. 
3. Lumhricina. 
II. Polychoita . . 1. Vagantia. 
2. Sedentaria. 
3. Haliscoleina.

other division of the animal kingdom.— F. J. B.
