Remarks

Shells of T. ellyae usually show the median spiral cord of the teleoconch emerging in the fifth/sixth whorl, rarely at the seventh whorl (Fernandes et al. 2013; Fernandes 2014). A few shells sampled from Baía da Ilha Grande (Rio de Janeiro State) and São Paulo State had the median cord emerging as early as the fourth whorl ( Fig. 96D ).
