Chief Boatswains, Chief Gunners, Chief Machinists, Chief Carpenters, Chief Sailmakers, Chief Pharmacists and Chief Pay Clerks wear on the collars of their blue service coats the same devices showing their corps as those already described to be worn upon the collars of their frock coats; and the same is true of the Warrant Officers, Boatswains, Gunners, Machinists, Carpenters, Sailmakers, Pharmacists, Pay Clerks and Mates.
Shoulder marks for officers are worn on the white service coat, mess jacket and overcoat to indicate the corps and rank of the wearer. These marks are of dark blue cloth lined with black silk, stiffened so as to lie flat, 4½ to 5¼ inches long and 2¼ inches wide, finished with a triangular point and a gilt Navy button at the collar end, and they are worn on the top of each shoulder extending from the base of the collar to the shoulder seam.
The designs for the different ranks are as shown in the illustrations. For officers of the Line they are as follows:
Admiral of the Navy—covered with gold lace braid two inches wide, with four silver stars, the two end stars being surcharged upon gold foul anchors.
