MATERIALEXAMINED. — SEAMOUNT 2, stn TS 267, 34°22.50’N , 30°22.50’W , 2225 m , 3 specimens , tl (cl) 7.0 (5.7) to 12.0 (9.3) mm ( MNHN Ci 2843, MNRJ 13896). REMARKS The present specimens have a scutum less reduced than those described in the original description ( Young 1998a: 8 ); the basal arm is shorter and the occludent arm is still calcified. The terga do not develop an undulated basal margin, which was also observed in a smaller specimen described previously. But all three of the present specimens have the capitulum with a typical triangular shape and the height 2.5 times its width. The differences in the calcification of the plates are considered different stages of development. Dichelaspis thieli was recorded from off Morocco from 1300 m . These new records extend its distribution to the Azores region and to depth between 1300 and 2225 m .
