Levinsen describes [h\) Dysponetus pygmmis, fam., g., & sp, nn. Parac- 
tius littoralis, fam., g., & sp. un. Eunicearum. The following are the 
diagnoses of the two genera : — 
Dysponetus. Corpus elongato-ovatum e segmentis paucis omnibus seti- 
geris compositum ; lobus cephalicus appendicibus brevissimis peduncu- 
latis septem instructus ; pedes biremes, remis bene sejunctis, dorsalibus 
Betas si mplices cirrosque elongates foliiformes, ventralibus setas compositas 
cirrosque minutes gerentibus ; branchiae nullae ; segmentum anale cir- 
rorum loco processu coniform! instructum; proboscis amphoriformis 
maxillis duabus elongatis antico anguste hastiforraibus munita. 
ParacAius. Corpus elongatum ; lobus cephalicus appendicibus brevibus 
inarticulatis quatuor instructus, quarum duae in parte dorsali, duae sub mar- 
ginibus lateralibus lobi cephalic! affixae sunt ; segmenta duo sequentia 
nuda ; pedes uniremes setas paucas (simplices et compositas gerentes), cirri 
nulli ; segmentum anale cirris duobus ejusdem formae ac appendices 
cephalicae ; proboscis maxillis inferioribus duabus maxillisque superioribus 
utrinque octo, quarum quatuor posteriores hamatae sunt. 
Greef (46) finds that Sagitella and A cicularia are distinguished from 
Typhloscolex by characters which are merely of specific value. If the 
presence of the anterior row of setas is not a specific character, we shall 
have : — 
(i.) T. muelleri {Sagitella howalevskii, Wagner, form 6; larva of A. 
virchowi, Greef, and S. harhata, XJlianin). 
(ii.) T. Jcowalevshii {S. kotvalevshii, Wagner, form a ; A. virchowi^ 
Langerhans ; S. kowalet^slcii, XJlianin). 
(iii.) T. XJlianin. • 
Cosmovici (40) adds a fourth to the hermaphrodite species of Spirorhis ; 
S. communis, which is very common at Roscoff. 
Vejdovsky (57) in the second, or systematic portion of his monograph, 
(1) defines the family Enchytrceidoe, and the three genera, Pachydrilus, 
Enchy trams, and Anachccta, the last name is to take the place of the name 
Achceta, already in use (as Acheta) among the Gryllidce ; in it the setas are 
replaced by gland-cells, the cephalic pore is at the most anterior end of 
the cephalic lobe ; there are no dorsal pores ; the segmental organs are 
modified into salivary glands in the 3-6 segments, and the testicular tubes 
are amorphous. 
Of the species, the following are now described for the first time, or 
were defined in the preliminary communication [Zool. Rec. xiv. Verm. 
p. 17] : — Pachydrilus fossor, P. sphagnetorum, Enchytrceus puteanus, E. 
leptodera, E. buchholzi, E. hermicultor (E. vermiculai’is, Ratzel), E. 
lohifer, E. adriaticus, E. p>errieri, E. leydigi, E. hegemon, Anachccta 
eiseni.
