Comments. The partial to total infilling of the 
hinge trough is one of the characteristic features 
of members of the Anakineticinae. Magadinella 
and young individuals of Anakinetica and Para- 
kinetica show that reduction in size and/or total 
infilling of the hinge trough is the result of en¬ 
largement of the cardinal process (anterior sur¬ 
face) which fuses anteriorly with the crural 
bases. Aliquantula shows a different mode of in¬ 
filling, with swollen crural bases which may be 
fused medially but which do not fuse with the 
cardinal process. As a result, a tiny posterior 
hinge trough is delimited. In characters of the 
cardinalia, Aliquantula closely resembles the 
Japanese genus Nipponithyris , but the latter dif¬ 
fers in beak characters and in loop pattern.

Description. Length of figured specimen (Fig. 6 
H-I, K-L) 28.8 mm, dorsal valve length, 25.4 
mm, breadth 22.1 mm, depth 12.4 mm. Outline 
ovate, biconvex. Anterior commissure slightly 
sulcate. Hinge platform outline ovate; socket 
ridges incurved, not projecting beyond valve 
margin; crural bases fused with anterior halves 
of socket ridges; posterior hinge trough small, 
deep: cardinal process almost circular in outline, 
anterior surface slightly swollen. Septum short, 
blade-like, without loop attachments. Ventral 
valve interior with heavily thickened postero¬ 
lateral walls, beak cavity reduced to narrow tun¬ 
nel. Hinge teeth irregular in outline, overlying 
heavy lateral thickenings in posterior region of 
valve immediately anterior to beak. 
Comments. Of Tate’s syntypes, specimen SAM 
T908A has previously been referred to Aldingia 
furculifera by Richardson (1973a).
