REMARKS

Only one small specimen with broken plates was collected during the MARVEL Expedition. It does not have the longitudinal ridges fully developed, especially on the tergum and scutum.

When reviewing the literature, I noted that different stages of peduncular development were figured by different authors ( Sars 1885; Broch 1924, 1953; Stephensen 1936; Tarasov & Zevina 1957; Nilsson- Cantell 1978). Their small specimens had an eightplate pattern of scales in two whorls (rl-cl and sr-l-sc) which is transformed in larger specimens to two whorls of approximately four to five similar plates. Verum striolatum is a common species from the Arctic Ocean ranging between 62°N and 80°N, and between 342 and 2700 m ( Zevina 1981: 222). This new sample extends significantly its distribution to the Azores region.
