Codrington PL 106 ; Gomes F3:16.01 ; KM #9.2
Obverse : Crowned Coat of arms of Portugal divides C Lº (Ceilão) within line-dotted-line circles
Reverse : Gridiron of Saint Laurence divides year I6 40 and flames below within line-dotted-line circles.

Gomes gives a weight range of 2.16-3.2 grams for this series.
The mint mark C Lº is attributed by Codrington to Ceilão or Colombo. The Portuguese fort at Colombo was the Fortress of São Lourenço. The emblem of Saint Laurence is the gridiron with the flames below on which he was martyr in 258 AD.
In Krause the flames are described as a Crown.

Codrington (VIII-21:I,p.99) lists it among silver coins struck in or for Ceylon as the first series struck in 1640 of the Gridiron type. He says The workmanship resembles that of the Goa mint, and these coins very probably may have been struck there for the use in the island or possibly locally with dies sent from the capital.

In Grogan section on Ceylon the Tanga is illustrated with
(1318) -- 17 mm and 2.60 grams
(1319) -- 16.5/16 mm. 2.39 grams
