Type material.

Syntypes, 2 females, 5 mm, ZMB 20319.

Type locality.

North Atlantic (17°28'N, 29°42'W), 3000 m.

Depth range.

0-4000 m ( Schellenberg 1926a, Hendrycks and Conlan 2003).

Distribution.

Atlantic Ocean: approximately 650 kms west-north-west of the Cape Verde Islands ( Schellenberg 1926a); west of South Africa ( Schellenberg 1926b).

Indian Ocean: approximately 1100 kms west-north-west of Cocos (Keeling) Islands ( Birstein and Vinogradov 1964).

Pacific Ocean: Kurile-Kamchatka region ( Birstein and Vinogradov 1970); United States, west of California ( Hendrycks and Conlan 2003).

Southern Ocean: Antarctica, approximately 600 kms north of the Oates Coast ( Birstein and Vinogradov 1962).

Discussion.

Scopelocheiropsis abyssalis was originally described and illustrated as lacking a mandibular molar. Hendrycks and Conlan (2003) described new material and indicated the presence of a small molar. We have re-examined one of the syntypes of this species and can confirm the presence of a molar on the type material (see Figure 36).
