Figure 3. A-N, Vermiliopsis cylindrica n.sp. (A) tube of holotype, AM W21406; B-G, a specimen from AM W21434: ( B ) whole worm, 
showing its short and broad chitinous operculum, its cap contracted into a concavity, with a central peak, and the extent of the thoracic 
membranes; (C) left ventrolateral view of thorax showing the ocellar cluster, termination of the thoracic membrane, the contracted proximal 
bulb-like part of the operculum, the peduncle, and numerous radioles; ( D ) enlarged drawing of operculum showing its transparent chitinous 
distal part, a single chamber with its terminal part contracted into a concavity, and peduncle contracted into several irregular folds; (£) 
the cushion-like swelling (pygidial gland) at the posterior end of abdomen; (F) thoracic uncini; (G) anterior abdominal uncini; (//,/) two 
views of the operculum of specimen from AM W21434 showing an un-contracted dome-shaped distal part, a single transparent chamber 
below it, its contracted proximal bulb-shaped part (partly into the transparent chamber), and contracted peduncle; (7) anterior end of a 
small juvenile specimen showing operculum and extent of thoracic membranes; ( K) tube fragment found together with a specimen from 
AM W21434 (doubtfully included here); confirmation necessary as to whether such a circular unattached part can occur in this species. 
L,M, specimen from AM W21434: (L) anterior end of worm; (M) operculum; both show an un-contracted proximal bulb-shaped part, 
and a cylindrical distal part, the latter consisting of 3 partitions preceding the terminal chamber; ( N) operculum of a specimen from AM 
W21471: it is similar to that of the preceding specimen, but has two partitions proximal to the cylindrical chamber.
