ture and reproduction of certain forms. 

 Special facilities were afforded for this 

 work and an assistant was detailed to help 

 with it. The observations will probably 

 extend over a number of years. Professor 

 Wilson will report progress from time to 

 time. 



Mr. W. D. Hoyt, instructor in biology in 

 the University of Georgia, continued the 

 work on the marine algre be'gnin by him 

 last season. The intermediate position of 

 Beaufort Harbor betAveen the northern and 

 southern regions, where extended observa- 

 tions have been made on the marine algte, 

 makes the study of the forms occurring in 

 the Beaufort region especially interesting 

 and important. That it is richer in algae 

 than has been supposed has been shown by 

 the work already done. During the season 

 twenty-five species were added to the list, 

 which now numbers sixty-nine. All the 

 species are represented by specimens in the 

 laboratory collection. Of the forty species 

 which are properly identified, two are 

 Schizophyce», four are Chlorophycefp, five 

 are Phaeophyceae, four belong to the Dic- 

 i,yotales and twenty-five are Rhodophyceae. 

 In the case of seventeen forms, the genus 

 only has been determined and in twelve 

 neither the genus nor species is known. 



Mr. F. S. Collins, ^lalden, I\Iass.. has 

 very kindly given valuable suggestions in 

 this work and assisted with the identifica- 

 tion of many forms. 



Mr. Hoyt has preserved material for 

 morphological work on certain forms and 

 conducted experiments on the branching of 

 Dictyota dichotoma induced by injury. 



Mr. C. A. Shore, instructor in biology in 

 the University of North Carolina, did for 

 the Beaufort Crustacea (exclusive of the 

 amphipods and eirrepedes) this season 

 what the year before he had done for the 

 Annelids— the collection in the laboratory 

 was gone over and, as far as was possible 

 with the availa])l(' literature on the subject, 



the specimens were identified. Poor speci- 

 mens were replaced with perfect ones and 

 specimens of unrepresented species were 

 added when the opportunity afforded. 

 According to the report made by Mr. Shore 

 at the end of the season, the collection now 

 contains specimens of ninety-one species of 

 Crustacea, seventy-.seven of which are iden- 

 tified. The identification cf four is doubt- 

 ful. In the case of eight forms the genus 

 only has been determined and two are en- 

 tirely unidentified. 



In the above number are included thir- 

 teen species collected in 1902 by the Fish 

 Hawk from the region between Shackleford 

 and Bogue Banks and the Gulf Stream. 



Twenty-two species were added to the 

 list this season and from the unclassified 

 specimens already in the collection thirty- 

 nine species were identified. 



'Mr. L. R. Cary, graduate student of 

 zoology in the Johns Hopkins University, 

 began work on the anthozoa. In connec- 

 tion with the regTilar natural histor^^ ob- 

 servations and collections, he recorded on 

 charts, provided by the laboratory for the 

 purpose, the local distribution and abun- 

 dance of each species. His report for the 

 season shows the collection to now contain 

 specimens of eight species of Alcyonaria, 

 nine Actinaria and three Madreporaria. 

 This number does not include the species 

 collected in 1902 by the Fish Hmvk (two 

 corals excepted), the "work on this collec- 

 tion not having been completed. Mr. Cary 

 also made observations on the budding of 

 Cylista leiicolena and will continue his 

 study this winter on the structure and his- 

 tology of this form and of the individuals 

 developing from buds. 



The actinian larva which has been found 

 from time to time in the tow at Beaufort 

 and which IMr. Cary succeeded in rearing 

 last season and which he described in No. 

 1, Vol. VII., of the Biological Bidlefin. 

 has been identified as that of Epizoanihus
