(All this material was muchmacerated.)(6) S. Mahlos Atoll, Mamaduwari, where it was very common under the beach sandstonemasses to the north of the island.(c) Male Atoll, Hulule. A single specimen was obtained from a hole in a coralmass dredged from 7 fathoms in the lagoon of Hulule Atoll. (Anterior end only.)External features. In Willey's specimen the proboscis was of a rich yellow colour,the collar bright orange and the body generally of a dull yellow colour. No observationson the colour of the Maldive specimens have reached me except of the single one fromHulule. Mr Stanley Gardiner noted that the colour here was uniformly pale lemon. Muchstress however cannot be laid on the difference in colour from Willey's specimen as thisHulule individual was represented only by the pre-genital part of the animal and was arather small specimen.The general appearance of the Maldive forms agrees closely with the figure given byWilley ('99, PL XXVII. fig. 8). The size also is about the same though the length ofthe proboscis as compared with the collar is on the whole slightly greater than in W^illey'sspecimen. The relative length of the branchial region to the collar is on the average about6, as in Willey's animal. In the single entire specimen in the collection the total lengthwas 215 mm. The branchial region is faiily constant in its length relative to the collar inindividuals of different sizes. The number of gill slits increases markedly with the size ofthe animal. These facts are brought out in the following table of measurements:
