Description Valves large, sub-rectangular in lateral view; sexual dimorphism well developed (males more elongate than females)....
Etymology silentium (1at.) = peace, silence; according to environment and surroundings of this species.
Description Valves large, sub-rectangular in lateral view; sexual dimorphism well developed (males more elongate than females). Anterior broadly convex and densely denticulate with short stout spines below midheight. Posterior blunt with 4-5 strong spines below midheight and several minor ones. Dorsal outline almost straight, very slightly tapering towards the posterior, with a distinct anterior hinge-ear (more developed in LV) and a large posterodorsal spine at the posterior cardinal angle (only in LV). Ventral outline almost straight with a slight concavity at the oral region. Valves in dorsal view posteriorly inflated, creating an arrowhead-like outline. Posterior part of outline serrate. Overlap of LV over RV at the anterior hinge element distinct. Ornamentation consisting of a shallow to sometimes very subdued polygonal reticulation. Muri narrow and sharp, densely covered with fine foveolae. Bottom of fossae covered with an extremely fine granulation. Lateral pores sieve type, sometimes conulate. Marginal pore canals simple and straight, approx. 30 anteriorly and 10-15 posteriorly. Ventrolateral ridge strong and deeply excavated with a large spine at its posterior end and two moderately strong spines following in a line. The ventrolateral ridge continues into the much less developed ocular ridge. No eye tubercle present. Dorsal ridge weakly developed. Bradleya-bridge absent. Internal features as for the genus (HORNIBROOK 1952: 38) [details]

Description Valves large, sub-rectangular in lateral view; sexual dimorphism well developed (males more elongate than females). Anterior broadly convex and densely denticulate with short stout spines below midheight. Posterior blunt with 4-5 strong spines below midheight and several minor ones. Dorsal outline almost straight, very slightly tapering towards the posterior, with a distinct anterior hinge-ear (more developed in LV) and a large posterodorsal spine at the posterior cardinal angle (only in LV). Ventral outline almost straight with a slight concavity at the oral region. Valves in dorsal view posteriorly inflated, creating an arrowhead-like outline. Posterior part of outline serrate.

Marginal pore canals simple and straight, approx. 30 anteriorly and 10-15 posteriorly. Ventrolateral ridge strong and deeply excavated with a large spine at its posterior end and two moderately strong spines following in a line. The ventrolateral ridge continues into the much less developed ocular ridge. No eye tubercle present. Dorsal ridge weakly developed. Bradleya-bridge absent. Internal features as for the genus (HORNIBROOK 1952: 38) [details]Diagnosis A large Bradleya species with a strong ventrolateral ridge that continues into the faint ocular ridge. Ornamentation of low relief, Bradleya-bridge absent. [details]
Etymology silentium (1at.) = peace, silence; according to environment and surroundings of this species. [details]
Remark Remarks: The present species is allied to Cythere dictyon described by Brady (1880) from the South Pacific Ocean, but differs in the coarser networks of crest in the posterior part. It is also allied to Bradleya cuneazea described by Hornibrook (1952) from off the Big King Island, but differs in the finer networks of crest in the anterior part. [details]
