m the first only in the absence of accessory tentacles. 3. Figs. I, 2, and 3 are from another form which I found ingreat abundance at Green Turtle in the Bahamas in May, 1886.The largest specimens were about an inch in diameter, withabout fifty or sixty large ocellate tentacles, and an equalnumber of accessory tentacles, and ocellate marginal clubs.The mouth is quadrate and the lips are simple, and the distalfourth of the radiating canal is not occupied by the gonad. Fig. 2 is from a specimen half an inch in diameter, withthirty-two primary tentacles. In young specimens there are very few marginal clubs, andthe accessory tentacles are distributed irregularly. Fig. 3 isfrom a specimen about a fourth of an inch in diameter, withonly one club and only eight primary tentacles. This form is very similar to L. ulothrix of Haeckel, fromwhich it differs only in the distribution of the accessorytentacles and clubs, which is regular in the adult Bahamaform, and irregular in L. ulothrix.

THE BEHAVIOR OF THE CENTROSOMES IN THEFERTILIZED EGG OF MYZOSTOMA GLABRUM,LEUCKART. WILLIAM MORTON WHEELER. The material of Myzostoma glabrum on which the followingobservations were made was collected at Naples during Feb-ruary and March of the current year. The work on the fecun-dation of the Qgg was brought to a conclusion in the laboratoryof the Institut Zoologique at Liege, and I gladly seize thisopportunity of thanking the director of the Institut, ProfessorEd. Van Beneden, both for his constant and friendly guidanceduring my studies, and for the many favors and privilegeswhich he so cordially bestowed upon me. A fuller account ofmy observations, with a discussion of the pertinent literature,will be published later. The minute eggs of Myzostoma glabrum were fertilized arti-ficially and killed in Flemmings fluid (weaker formula). Thesections (5/* thick) were stained on the slide with Heidenhainsiron-alum haematoxylin, followed by a saturated aqueous solu-tion of Orange G. The larg
