Type Locality 
19°59'S, 117°16'E (off Port Walcott, WA); 50- 
52 m. 
Description 
Anthocyathus: Angle of straight, rounded 
thecal edges 94°-127°; angle of thecal faces 23°- 
32°. Largest specimen (the holotype) 56.5 x 17.6 
mm in calicular diameter and 26.9 mm in height, 
with a basal scar diameter of 17.7 x 6.5 mm. 
Calicular edge and basal scar strongly arched, 
both roughly concentric to the point of 
attachment of anthocaulus; GCD:LCD = 3.0-3.2. 
Basal scar ranges from 14.4 to 18.3 mm in greater 
diameter (ave. = 15.85, N = 14). One pair of 
downward curving thecal edge spines occurs 
directly adjacent to basal scar; thecal spines up 
to 7 mm in length but usually broken or worn in 
larger coralla. Theca often encrusted with 
calcareous epifauna, including bryozoa, 
serpulids, and foraminifera; otherwise corallum 
uniformly white. Septa hexamerally arranged in 
6 cycles (S1-4»S5>S6, =192 septa), the sixth 
cycle complete at a GCD as low as 36 mm. 
Larger coralla (>50 mm GCD) often have 
additional primary septa (e.g., 50 equally large 
septa instead of 48, and some pairs of S7), the 
holotype having a total of 212 septa. Sl-4 shaped 
as in T. spheniscus and T. angiostomum: notched 
near the calicular edge, slightly exsert, slightly 
constricted midway to columella, and broader 
near columella. Axial edges of Sl-4 finely 
sinuous. S5 quite narrow at calicular edge, but 
widen to 2/3 width of Sl-4 lower in fossa. S6 
rudimentary. Fossa deep and elongate, 
containing a well-developed trabecular columella 
about 1.5 mm in width. 
Anthocaulus 10-12 mm in height and 1.7-2.0 mm 
in pedicel diameter, having 1 pair of elongate 
thecal edge spines. 
Remarks 
Truncatoflabellum veroni is similar to T. aculeatum 
(see Table 4), but can be distinguished by having a 
larger basal scar size, a higher edge angle (usually 
over 90° vs less than 90°), and more septa. Except 
for T. macroeschara, it has a largest basal scar 
diameter of any species in the genus. 
Distribution 
Western Australia: continental shelf of 
northwestern coast from Cape Jaubert to Onslow; 
40-119 m; sandy substrates. Elsewhere: Northern 
Territory (Anson Bay and Beagle Gulf); 15-31 m; 
coarse sand and gravel substrates. 
Etymology 
This species is named in honour of J. E. N. 
"Charlie" Veron, who has done much to advance 
our knowledge of Australian reef corals and who 
published several first records of azooxanthellate 
corals from Australia (Veron 1986).
