37 a. Var. himalayana.
Lophopus lendenfeldi, Annandale (nec Ridley), J. As. Soc. Bengal, (n. s.) iii, 1907, p. 92, pl. ii, figs. 1-4 (1907). Lophopus lendenfeldi var. himalayanus, id., Rec. Ind. Mus. i, p. 147, figs. 1, 2 (1907). Lophopus himalayanus, id., ibid. ii, p. 172, fig. 4 (1908).
This variety differs from the typical form in having fewer tentacles and in the fact that the marginal processes of the statoblast are abortive or absent.
Pectinatella davenporti, Oka[[BL]] from Japan is evidently a local race of L. carteri, from the typical form of which it differs in having the marginal processes of the statoblast more numerous and better developed. The abortive structure of these processes in var. himalayana points to an arrest of development, for they are the last part of the statoblast to be formed.
Types. The statoblasts mounted in Canada balsam by Carter and now in the British Museum must be regarded as the types of the species named but not seen by Hyatt. The types of the var. himalayana are in the Indian Museum and those of the subspecies davenporti presumably in the possession of Dr. Oka in Tokyo.
Geographical Distribution.—The typical form occurs in Bombay, the W. Himalayas and possibly Madras, and its statoblasts have been found in E. Africa; the var. himalayana has only been taken in the W. Himalayas and the subspecies davenporti in Japan. Indian localities are:—Bombay Presidency, Igatpuri Lake, W. Ghats (alt. ca. 2,000 feet); the Island of Bombay (Carter): W. Himalayas, Bhim Tal, Kumaon (alt. 4,500 feet).
