Besides the species mentioned, Malmgren describes as new three other 
species of Ampharete, viz. : A. goesiy p. 364 ; A, arcticay p. 364 ; A. gracilisy 
p. 365 y and Ampkicteis sundevalliy p. 366. 
Terebellacea. 
Malmgren (/. c.) divides this family as follows : — 
Subfamily I. Amphituitea (p. 373). Lobus cephalicus brevis truncatus 
antice tentaculis numerosis longitudinaliter canaliculatis marginibus conni- 
ventibus plus minusve elongatis sat numerosis, pone tentacula margine ver- 
tical! saepe pimctis nigris oculis dictis postice praedito, infra tentacula in 
labium os supra tegens antice productus. Vasa sanguifera conspicua. 
Branchiae saepissime adsunt. Setae capillares plus minusve limbatae, saepis- 
sime mode in anteriore parte corporis, interdum per totum corpus obviae. 
Uncini in toris iusidentes, aviculares vel rarius pectiniformes, per totum 
corpus eadem forma. 
Subfamily II. Polycirbidea (p. 390). Lobus cephalicus labium magnum 
integrum vel rarius tripartitum formans supra prope marginem tentaculis 
numerosissimis canaliculatis obsitum. Setae capillares baud limbatae, stepis- 
simo tantummodo in anteriore parte obviae. Uncini aut hamati aut elongati 
sublineares, aut nulli. Branchia3 nullae. Oculi nulli. Vasa sanguifera nulla 
conspicua. 
Subfamily III. Artacamacea (p. 394). Segmentum buccale antice in 
proboscidem magnam papillosam productum. 
Subfamily IV. Trichobranchidea (p. 395). Lobus cephalicus ut in 
Amphitriteis. Branchiae liliformes. Uncini in anteriore parte corporis ros- 
trati, in posteriore aviculares. 
Subfamily V. Oanephoridea (p. 396). Branchia sola quadripartita pec- 
tinata. Uncini in anteriore parte corporis rostrati, in posteriore pectini- 
formes. 
Subfamily I. Amphitritea. 
A. Fasciculi setarum capillarium modo in anteriore parte corporis. 
1. Branchiae ramosae. 
a. Branchiarum paria tria. 
a. Branchiae fere aequales, subfr’uticosae : 
Amphitritc (Miill.). 
/3. Branchiae arborescentes, postice sensim breviores, 
aa. Uncini pectiniformes : 
Loimitty g. n., p. 380 j type Terehella medusa (Sav.). 
hh. Uncini aviculares. 
aa. Segmentum buccale in labium magnum latumque productum : 
LanicBy g. n., p. 379 j type Nereis conchilega (Pall.).
