Fobnson Fund SLATION RECORDS OF THE FIRST JOHNSON-SMITHSONIAN DEEP-SEA EXPEDITION By PAUL BARTSCH U.S. National Museum; Director of the Expedition (WitTH ONE Prater) The Johnson-Smithsonian Deep-Sea Expedition to the Puerto Rican Deep was sponsored by Mr. Eldridge R. Johnson, of Philadelphia, who placed his beautiful yacht Caroline at the disposal of the Smith- sonian Institution and equipped her with the instruments necessary for the work. We were provided with the best of sonic sounding | apparatus, thanks to the assistance of the United States Navy, and with an equally efficient winch, water bottles, and thermometers for hydrographic studies, enabling us to work at any depth. A dredging winch suitable for reaching profound depths could not be had within the time available for equipping ; we therefore had installed a tempo- rary winch carrying 6,563 feet of $-inch Special 6x 19 Monitor strand wire rope. This is mentioned merely in explanation of why work in greater depths was not done. In the next cruise this handicap will be obviated. The first bearing cited with each station marks the position of the ship at the beginning of the haul, and the second bearing indicates the position at the close of the haul. The bearings were taken by Capt. Andrew H. Peterson and his associated officers: Victor Johnson, chief officer; Hjalmar Iversen, second officer; Gunnar Bergersen, third officer. The radio beacon bearings were obtained under the captain’s di- rection by Thomas W. Braidwood, senior radio operator, and Louis G. Fullerton, junior radio operator. The sonic sounding operations were conducted by T. Townsend Brown, of the Naval Research Laboratory, Washington, D. C., assisted by E. R. Fenimore Johnson, Anthony Wilding, and the Misses Ena and Florence Douglass. The soundings as here cited are unreduced, using as the basis for notation a 400 fathoms per second interval. These soundings will, therefore, when eventually corrected, record a considerably greater depth than here indicated. We are deeply indebted to the Hydrographic Office of the United States Navy for the preparation of the accompanying chart. SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 91, No. 1 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI STATION 1. Lat. 18°33'45” N. Long. 66°15’00” W. January 30, 1933 From the above position, which is about 5 miles off Punta Boca Juana with Morro Castle Light bearing 126°, about 9 miles from the light, we lowered a 35-foot 4-inch mesh otter trawl into 400 fathoms at II: 30 a.m. Going north, we passed over soundings of 380 and 360 fathoms, then dropped off to 600 fathoms, when the net was hauled in and landed at 2: 45 p.m. The catch consisted of 64 fish, a small lot of mollusks, a few brittle- stars, two solitary corals, and a few other things. STATION 2. Lat. 18°31'20” N. Long. 66°16'20” W. January 30, 1933 From the above position, which is about 2 miles off Punta Boca Juana and g miles from Morro Castle Light, which had a bearing of 110°, we dropped a g-foot beam trawl in 200 fathoms at 4: 10 p.m. We moved in a northwesterly direction for about a mile, changing gradually to a depth of 240 fathoms, and landed the trawl at 4:55 p.m. The depth ranged from 200 to 240 fathoms. This was almost a water haul, owing to the fact that the trawl was lowered while the ship was practically at a standstill, causing the heavy frame to sink more rapidly than the net even with its tail weight, with the result that when the frame came to anchor on the bottom, the tail weight with the net overlapped the opening of the dredge and closed it. However, the haul yielded a lot of glass sponges, a pennarian, and a few brittlestars attached to the webbing. STATION 3. Lat. 18°31’30” N. Long. 66°21'30” W. January 31, 1033 Lat. 18°31'20” N. Long. 66°22'30” W. Punta Cerro Gordo bore 156° and Garza Island 212°. We lowered a 9-foot beam trawl, which struck bottom at 10: 30 a.m. in 200 fathoms, and hauled to the second position given above in 260 fathoms, landing the net at II a.m. This was purely a water haul, yielding nothing. STATION 4. Lat. 18°31’45” N. Long. 66°24’00” W. January 31, 1033 Lat. 18°31'45” N. Long. 66°26’30” W. Punta Puerto Nueva bore 180° and Garza Island 151°. We again dropped the 9-foot beam trawl at 11: 45 a.m. in 260 fathoms and began hauling in at I: 30 p.m. from 160 fathoms at the second position noted above. At the time Punta Chivato bore 182° and Punta Tortuguera 220° In this haul rough bottom was encountered ; the shackle parted and all the gear was lost. At the end of the wire cable a bit of mud adhered, which held a valve of a scallop (Amusium). The depth ranged from 160 to 260 fathoms. NO. I IST JOHNSON EXPEDITION: STATIONS—-BARTSCH 3 STATION 5. Lat. 18°37’00” N. Long. 66°24'30” W. January 31, 1933 The above is the stopping place of the dredging operations during this haul. The bearing at the start was not recorded. For this haul a modified young-fish trawl, operated by the hydro- graphic winch, was used. A rectangular #-inch pipe frame, 3 by 6 feet in size, was substituted for the otterboards. The net was let down at 3 p.m. in 600 fathoms with 3,000 meters of wire out. We held course I15° by gyrocompass until 4 p.m., when the cable was started in, the net reaching the deck at 4: 35. This haul yielded 396 small deep-sea fish, three species of pteropod and one of heteropod mollusks, a host of small crustaceans, some sagitta, a few medusae, and some fish eggs. STATION 6. Lat. 18°30’45” N. Long. 66°04’30” W. February I, 1933 Lat. 18°30’50” N. Long. 66°o1'15” W. A modified young-fish trawl was put overboard at 9: 55 a.m. Morro Castle Light bore 231° and the west end of Cabras Island 240°. When the hauling in began at 10: 50, Morro Castle Light bore 248° and the dome of San Juan Capitol 242°. The haul was made in about 100 fathoms and resulted in the capture of a small number of fish; some small pelagic mollusks, including a small octopus, heteropods, and pteropods ; and a small lot of crustaceans and salpae. STATION 7. Lat. 18°30'45” N. Long. 66°00’50” W. February I, 1933 Lat. 18°31'00” N. Long. 65°55’15” W. We lowered an otter trawl with new large boards at 11:35 a.m. Punta Cangrejos bore 161° and Punta Vacia Talega 120°. At the close of the haul Punta Vacia Talega bore 159° and Punta Cangrejos 235°. The depths of this haul ranged from 160 to 340 fathoms. During the middle of the haul there was a vicious jerk, indicating that the gear snagged. When we landed the net, it was found that one of the otterboards was lost and the trawl completely wrecked. A single umbellula caught in the wreckage rewarded us for our efforts. STATION 8. Lat. 18°31’30” N. Long. 65°55’30” W. February I, 1933 Lat. 18°33/15” N. Long. 65°56’45” W. When we lowered the modified fish trawl at 1:35 p.m., Punta Vacia Talega bore 165° and Punta Morro 255°. When the trawl was taken in, Punta Vacia Talega bore 165°, Punta Morro 246°. The haul was made in about 300 fathoms. The trawl evidently struck heavy mud bottom and filled with enough of the mud to completely rip out the webbing. 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QT STATION 9. Lat. 18°31'30” N. Long. 65°55'30” W. February I, 1933 Lat. 18°30’20” N. Long. 65°57’00” W. At the start Punta Vacia Talega bore 168°, Punta Morro 255°. At the close of the haul Morro Castle Light bore 254° and Punta Maldonado 205°. A 9-foot beam trawl was lowered at 3:25 p.m. and hauled in at 4:00 p.m., the depth ranging from 240 to 280 fathoms. Although no snagging was noticed on the accumulator, the net, when brought aboard, was completely ripped apart. The fragments of webbing contained a few brittlestars, some worm tubes, a beautiful hydroid, and a few mollusks. STATION 10. Lat. 18°20'20” N. Long. 66°05’30” W. February 2, 1933 Lat. 18°30'24” N. Long. 66°04'15” W. At the start, at 9:55 a.m., Morro Castle Light bore 242° and the west point of Cabras Island 255°. When we hauled in at 10: 35 a.m. Morro Castle Light bore 259°, Cabras Island 264°. The depth varied from 120 to 160 fathoms. For this haul we used a 9-foot tangle in about 100 fathoms of water, the tangle consisting of 16 loops, 6 feet long, of 2-inch frayed hawser. The catch was eminently successful, yielding many mollusks, brittle- stars, a sea urchin, sand dollars, a crinoid arm, holothurians, many crustaceans, hydroids, corallines, sponges, and many algae. STATION 11. Lat. 18°32’15” N. Long. 66°04’10” W. February 2, 1933 Lat. 18°32'50” N. Long. 66°o1'00” W. At the start Morro Castle Light bore 220° and Cabras Island 228°. At the close of the haul Morro Castle Light bore 234° and Punta Cangrejos 167°. A modified young-fish trawl was put overboard at II: 15 a.m. in 200 fathoms of water and was hauled in at 12: 10 p.m. This haul yielded many small fish, two small cephalopods, a few pelagic mollusks, and many crustaceans. STATION 12. Lat. 18°31’00” N. Long. 66°00’15” W. February 2, 1933 Lat. 18°30’30” N. Long. 66°01’45” W. At the start, 12: 30 p.m., Morro Castle Light bore 249° and Punta Maldonado 158°. When the trawl was taken in at 1: 30 p.m. Morro Castle Light bore 245° and Salinas Island 256°. A g-foot beam trawl was used in 200-300 fathoms. This haul yielded many mollusks, crustaceans, some holothurians, brittlestars, a glass sponge, three small corals, and a lot of blue mud. NO. I IST JOHNSON EXPEDITION: STATIONS—BARTSCH 5 STATION 13. Lat. 18°31’05” N. Long. 66°02’15” W. February 2, 1933 Lat. 18°30’30” N. Long. 66°04’05” W. A 9-foot beam trawl was lowered at 1:30 p.m. and surfaced at 2:36 p.m., the depth ranging from 200 to 300 fathoms; the bottom was blue mud. The catch consisted of some fish, many mollusks, echinoderms, and hydroids, as well as mud. STATION 14. Lat. 18°31'00” N. Long. 66°04’10” W. February 2, 1033 Lat. 18°30'30” N. Long. 66°03'15” W. A 6-foot beam trawl was lowered at 2:55 p.m. and raised at 3:45. The haul was made in 240 to 340 fathoms. It yielded some fish; many mollusks ; echinoderms, among them a large rose-red holothurian ; worms ; and crustaceans. STATION 15. Lat. 18°31'45” N. Long. 66°03’00” W. February 2, 1933 Lat. 18°30’30” N. Long. 66°03'15” W. At the start, 3:55 p.m., Morro Castle Light bore 231° and Punta Salinas 249°. At the close at 5.10 p.m., Morro Castle Light bore 229° and Punta Salinas 257°. An otter trawl was used in about 300 fathoms and did not touch bottom—at least, not for any length of time. It yielded a small number of deep-sea fish and crustaceans. STATION 16. Lat. 18°29’40” N. Long. 66°08’30” W. February 3, 1033 Lat. 18°31’00” N. Long. 66°10’15” W. At the start, at 9:07 a.m., the west point of Cabras Island bore 176°, Morro Castle Light 139°. When the haul was surfaced at 9: 50, the west point of Salinas Island bore 222° and Morro Castle Light 121°. The tangles were used in this haul at a depth ranging from 38 to 95 fathoms. The catch consisted of sponges; hydroids; corals; echinoderms, including comatulid crinoids ; and many mollusks. STATION 17. Lat. 18°30’00” N. Long. 66°10'30” W. February 3, 1033 Lat. 18°30’00” N. Long. 66°12'20” W. When the 6-foot trawl was lowered at 10: 00 a.m., the east point of Salinas Island bore 188° and Morro Castle Light 117°. When the trawl was taken up at 10: 40, Morro Castle Light bore 109° and the west point of Salinas Island 145°. The haul was made in a depth ranging from 46 to go fathoms. The catch produced a lot of hydroids, brittlestars, crinoids, and worms. 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI STATION 18. Lat. 18°30'15” N. Long. 66°12’45” W. February 3, 1933 Lat. 18°30'30” N. Long. 66°14’50” W. When the 6-foot beam trawl was lowered at 11:00 a.m., Morro Castle Light bore 109°, west point of Salinas Island 138°. When the trawl was surfaced at 11:40, the west point of Salinas Island bore 119°, Punta Cerro Gordo 258°. The depth ranged from 39 to 80 fathoms. The result was a water haul. STATION 19. Lat. 18°31’10” N. Long. 66°15'45” W. February 3, 19033 Lat. 18°32’30” N. Long. 66°19'35” W. An otter trawl was lowered at 11:54 a.m., the west point of Salinas Island bearing 120°, Punta Cerro Gordo 256°. When the trawl was taken up at I p.m., Punta Cerro Gordo bore 193°, and the west point of Salinas Island 115°. The depth of the haul ranged from 200 to 420 fathoms. The catch yielded a few deep-sea fish, a young mackerel, and a couple of small puffers ; also a few salpae and a larval crustacean. STATION 20. Lat. 18°40’30” N. Long. 66°19’00” W. February 3, 1033 Lat. 18°38’30” N. Long. 66°25'45” W. A modified young-fish trawl was put overboard at 3:05 p.m., Morro Castle Light bearing 138°, Punta Cerro Gordo 187°. When the trawl was surfaced at 5: 40, the depth recorded for the bottom was 960 to 1,000 fathoms. Owing to a kink in the wire, caused by the winch jumping a sheave in the winch room, we lost abcut 100 fathoms with the net. While the last haul was in progress, a pair of Carachodon sharks played about the stern of the ship. A bait put overboard was soon snapped up, and Dr. Price and Mr. Weber were able to perform a postmortem which yielded a lot of copepods and a tapeworm from the stomach and one tapeworm from the intestines.

When it was brought in at 4:00, the east point of Salinas Island bore 112° and Punta Cerro Gordo 206°. The haul was made in 260 to 350 fathoms. The net came up in tatters and yielded very little except a small lump of mud, a pennarian, and a few crustaceans and mollusks. STATION 25. Lat. 18°32'15” N. Long. 66°22’10” W. February 7, 1933 Lat. 18°32’05” N. Long. 66°22’10” W. A 3-foot dredge was put overboard at 9:45 a.m., when Salinas Island bore 109°, Punta Cerro Gordo 157°. When the dredge was surfaced at 10: 35, Salinas Island gave a bearing of 108° and Punta Cerro Gordo 149°. This haul was made in 240 to 300 fathoms. It yielded a bagful of soft, oozy mud, which contained a few ascidians, a splendid lot of many kinds of mollusks, a few crustaceans, a few corals, and many foraminifera. 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.

We tested the thermometer by placing it in the cold mud; it registered 23° C. February 23, 1933 We came to anchor off Playa de Fajardo, Puerto Rico, and after dark we tried our new circular net and 8-foot ring with bobbinet net, illuminating the area over this net with the cargo light provided with powerful lamps. In spite of the fact that this is one of the poorest places on the coast of Puerto Rico for life, on account of the volcanic ash bottom, we obtained rather good results, catching a number of fish, among them a cutlass fish about 30 inches long, NO- IST JOHNSON EXPEDITION: STATIONS—BARTSCH ge) which carried a fish in its mouth when surfaced. This was a most voracious fish, snapping at everything with which it came in contact. In addition to the fish, we obtained a mass of small material. Examin- ing the fish for parasites kept Dr. Price busy until 1 o’clock in the morning. February 24, 10933 At daylight, Fenimore Johnson, Dr. Darby, Dr. Price, Mr. Weber and myself visited Palominos Island, which we found composed of ancient rock, a very poor environment for shell collecting.

This haul was made in about 360 fathoms, 1,000 fathoms of cable being paid out. In the otter trawl we had placed an intermediate bobbinet net. The haul yielded a number of deep-sea fish, some very brilliantly colored crustaceans, two octopuses, and a small number of mollusks. While we were making the last haul, a shark 40 inches long, having a basal caudal notch like that of a tiger shark, was caught ; parts of it were preserved. We came to anchor opposite Icacos Cay for the night and after dark made a small collection of fish, crustaceans, and worms, with the use of the cargo light and submarine light and the big circular net, as well as dip nets. February 25, 1033 During the night an 114-foot shark weighing 660, pounds was caught; we found it on the hook next morning. We also caught a remora, which was swimming about the shark. Both of these were examined by Dr. Price for parasites. The shark proved to be a female bearing 39 young of considerable length. At about 7:30 a.m., Mr. Douglass, Florence Douglass, Dr. Price, Mr. Weber and the writer went to Lobos Island and made a collection of shore species of mollusks, crustaceans, and other forms.

Nine hundred fathoms of cable was paid out, the haul being made, therefore, in at least 300 fathoms. The area trav- ersed ranged from 100 to 300 fathoms in depth, the result being that the tail end of the otter trawl was torn out. From the remaining webbing we obtained a mass of sticky mud containing a pecten and an isopod. We had undoubtedly overloaded the dredge with the bottom mud and thus ripped out the end. February 25, 1933 We came to anchor in Luispena Channel off Culebra Island and after dark put the 8-foot net overboard and used the cargo lights. With it and the deep nets we caught a mass of small fish and a squid. We also made a tow with the 4-foot bobbinet net, using the port launch, and caught a mass of minute forms. February 26, 1033 Shortly after 6 o'clock, Fenimore Johnson, Dr. Darby, Mr. Douglass and his two daughters, Dr. Price, Mr. Weber, and the writer paid a visit to Flamingo Lake in the interior of Culebra Island, which we were told was swarming with ducks. This slightly brackish lake has been formed by the piling up of shore debris at the entrance to a gully on its sea side to form a hurricane rampart. It is probably a quarter of a mile across in its largest diameter, is shallow, and contains an abundance of vegetation, largely Chara. The lake was literally swarming with ducks. There must have been several thousand, most of them being lesser scaup. The rest were bahama ducks, and among these was a sprinkling of coots, great blue herons, little blue herons in various phases of coloration, and green herons. There was also a huge flock of lesser yellowlegs, a smaller number of turnstones, some spotted sandpipers, and the usual number of native species of land birds, as well as man o’ war hawks, brown pelicans, etc. From the shores of this lake we gathered some algae, fiddler crabs, and a few minute mollusks.

We had 1,000 fathoms of cable out, which meant that the depth was probably 300 to 350 fathoms. This was a remarkable haul, yielding a lot of deep-sea fish, among them two very beautiful lantern fish. There were also a lot of mollusks, as well as comatulid crinoids and many other forms. The capture of the crinoids and mollusks indicated that bottom was reached, but it must have been touched very lightly, for no damage to the gear was noted. 24 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.

From these three depths the chamber was returned intact. As the echo sounding machine failed to give us an answer, we believed that we were in still deeper water and so lowered the pressure chamber to 4,500 fathoms. A kink developed in the wire, which in passing through the sheave on hauling up caused the wire to break, and we lost the chamber. While this work was being done, the ship was adrift. Two sharks were caught, which appear to be Carcharodon; they were post- mortemed by Dr. Price for parasites. One of the sharks was ac- . companied by two pilotfish, which we caught by leading the shark into the circular net, the fish following. Lat. 19°30’30” N. Long. 65°14’00” W.

It is probable that the treating of the hydrographic stranded wires with a mixture of linseed and kerosene oils proved a deterrent to the fish. STATION 89. Lat. 19°13’00” N. Long. 65°16’00” W. February 28, 1933 The day being calm and the sea almost as smooth as glass, we decided to try out our Nansen water bottles and reversible ther- mometers. Six sets of Nansen bottles, each provided with two ther- mometers, were lowered in series, to 500, 1,000, 2,000, 3,000, 4,000 and 4,500 meters, and yielded splendid results as to water and tem- perature readings, which will be reported on separately. While this work was going on, the launch picked up a tubful of sargassum, which upon being washed with fresh water and shaken. yielded a number of fish, crustaceans, and mollusks. STATION 90.

February 28, 1933 A small circular dredge, with a bucketlike rim and handle frame an inch in width and a foot in diameter, with a double net 23 feet long, one bobbinet and the other 43-inch webbing, was lowered to 3,000 fathoms. The ship was then moved slightly ahead while another 1,000 fathoms of cable was paid out. On hauling in, it was found that the net had indeed struck bottom, but the wire cable, unfortu- nately, had been too profusely supplied and had kinked, so that a large amount of it had to be abandoned on account of the kinking. The net itself contained a bit of sticky mud and a single fragment of an Oliva. While these operations were going on, another tiger shark was captured, a moderate-sized specimen, and later still another, probably a Carcharodon. Both of these were examined by Dr. Price and Mr. Weber for parasites, and parts of the animals were preserved. STATION 91. Lat. 18°37’30” N. Long. 65°05’00” W. March I, 1933 Lat. 18°42’00” N.

We came to anchor at Brewers Bay, St. Thomas, and after dark Mr. Weber and Miss Florence Douglass used the submarine light at the gangway and obtained a splendid lot of fish, four small squids, some shrimp, and other crustaceans. We also used the cargo light 26 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI and the 8-foot circular net, but the strong current prevented its successful operation.

The haul was made in depths ranging from 90 to 500 fathoms. This was by far the most important station. The dredge came up with a mass of material, among which were two dozen exquisite NO.

There were also a lot of comatulids and some beautiful specimens of Astrophyton attached to hydroids. We likewise obtained a host of deep-sea fish, mollusks, brachiopods, crustaceans, sponges, hydroids, anemones, worm tubes, etc. Dr. Price obtained a number of parasites from larger fish. STATION 103.

An otter trawl was lowered at 4: 42 p.m. and surfaced at 6: 10, the water varying from 150 to 400 fathoms in depth. During this haul, the accumulator indicated that we had snagged, and upon surfacing the line, it was found that only the bridle of the otter trawl was present, the boards and the net having been torn away. On the rope, however, there was a piece of a hydroid containing an Astrophyton. Beginning in the evening and continuing until the next morning, T. T. Brown and Fenimore Johnson, assisted by Anthony Wilding and Ena and Florence Douglass, took soundings. These extended over two lines parallel to the one previously made, one 20 miles to the north and another 20 miles to the south. Soundings on these lines were also spaced at 5-mile intervals. The former middle line was also extended east to coincide with these two parallel lines. The three, therefore, are 235 miles in length. There was also a line of soundings run north from the last dredging station to the parallel sounding lines, on which stations were made at 5-mile intervals. All these, together with their depths, are plotted on the accompanying chart. A detailed report of these soundings with bearings will be published in a separate paper. STATION 104. Lat. 18°30’40” N.

When we lowered the Chesapeake Bay oyster dredge at 8: 53 a.m., Morro Castle Light bore 111° and the western end of Salinas Island 136°. When it was surfaced at 9:41, the western end of Salinas Island bore 121° and the eastern end 116°. The depth ranged from 80 to 120 fathoms. We had lined the chain-linked oyster trawl with 43-inch webbing, and the haul brought up a bagful of bottom, containing a host of mollusks, crustaceans, crinoids, sponges, and other forms. 30 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.

When the oyster dredge was again lowered at 10:09 a.m., Morro Castle Light bore 113° and the west end of Salinas Island 138°. When it was surfaced at 10:51, Morro Castle Light bore 113° and the west end of Salinas Island 129°. The haul was made in 150 fathoms. By the time the dredge reached the surface, most of the material had been washed out of the bag, but an interesting lot of fish, mol- lusks, crustaceans, echinoderms, worms, and hydroids were present.

When it was surfaced at 12:03 p.m., Morro Castle Light bore 106° and the west end of Salinas Island 113°. The depth of this haul ranged from 150 to 195 fathoms. The material was again largely washed out of the dredge, but there remained a lot of mollusks, brittlestars, anemones, and other forms. STATION 107. Lat. 18°32'15” N. Long. 66°17’45” W. March 8, 1933 Lat. 18°32’30” N. Long. 66°22'45” W. When the otter trawl was put over at 12:57 p.m., Morro Castle Light bore 112° and the west end of Salinas Island 120°. When it was surfaced at 2:34, Punta Cerro Gordo bore 145° and Garza Island 182°. The haul was made in 250 to 260 fathoms. A tremendous pull on the accumulator indicated that the apparatus had snagged, and upon hauling in, we found we had lost all the gear. On the way north we made a series of soundings across the great deep, which are indicated on our chart. STATION 108. Lat. 19°32’00” N. Long. 67°53’00” W. March 9, 1933 At this station on the north side of the deep, a depth of 2,940 fathoms was sounded. We put a series of Nansen water bottles over, but the heavy swell caused us to drift too rapidly to effect a straight line. We therefore lowered only four bottles with thermometers to depths of 500, 1,000, 1,900 and 2,400 meters. Water samples and thermometer readings were obtained at this station, an account of which will be given later. NO. I IST JOHNSON EXPEDITION: STATIONS—BARTSCH 31 STATION 109. Lat. 20°05’00” N.

The drift of the ship, caused by the wind, again prevented us from reaching bottom. The sounding given was 2,900 fathoms. The few forms caught in the Johnson bucket dredge were pelagic organisms and were probably captured on the upward pull. ra) MA eh. | a Arete’: Cae ae ‘ AGyiA® % : . oy ory Rens et. re hoa es eee (EF ie oe rd or ¢ - a en: € : ’ ~ Pipe cee DEEP-SEA EXPED 30 360 350 CS soe LS 300° ra 240 360,09 PSone? f° 58 200 360,99 3 160, 60 “ Pe we: >) Cabo Cabron e ~ = 2 3200° a o ° (I ° “4 > oe = 1 ° 4 2 ) Cabo Samana © S eos ° = . 60 e ° oO . 360° = ° A . . | PtaMangle <—Jaatendra Ho ne a a +, Cayo Levantad aaHia cae %, r ey, Wo, “rar, trae ia 2h 8 ae 5 os, J y | > Pach + Se afaih ie) 6 “Scarras Isletsiby \o LDesecheo O pee Gordal ; ae ra Pt Z J fs) C <5. ° A : S° Gi ‘ =" ks “or Patani erst 2 — Savanal. 9 ; A a Culebra bene ens oa Coa 0 2 . oy 7 50 ‘i 4 47 ' ——— aa | ce 0 er ; ts © Farallon Pk E) se | LMonitos 49. —8— | North Cape = East Cape ' == - SP _ —— pase = == = = 8 | | | | The soundings in these records are unreduced, using 2 400 fathoms per second standard. ill | | | Scale :/° Longitude equals 43 inches a) | | | | ie) | T ez | | 5 _ a i | | | \ )} ers y a 69° ; 5 —-—_ = _———— = | | l | : | = L ps al 1°30 30 68 30’ 67° 30 66° 30' 65° 30° 64 Prepared and Printed for the Smithsonian Institution By the Hydrographic Office, U.S. Navy. 4 | ; H y $ bh i ' ; oe Ep erie ec Re eee Ne SR Pn, on) ee ee ae fa a i ake we _ a oS rt OP ee oar.

PUERTO RICAN DEEP NEW MOLLUSKS OF THE FAMILY TURKETID AL (WirH ErcHtT PLATES) BY PAUL BARTSCH Curator, Division of Mollusks and Cenozoic Invertebrates, U.S. National Museum (PUBLICATION 3229) CITY OF WASHINGTON PUBLISHED BY THE SMITHSONIAN INSTITUTION MAY 29, 1934 The Lord Waftimore (Press BALTIMORE, MD., U. 8 As Zobnson Fund NEW MOLLUSKS OF THE FAMILY TURRITIDAE By PAUL BARTSCH Curator, Division of Mollusks and Cenozoic Invertebrates, U.S. National Museum (WitH E1cutr Priates) The first Johnson-Smithsonian Deep-Sea Expedition devoted its attention to the great deep of the Atlantic—the Puerto Rican Deep, a region faunally decidedly unexplored. The reason why this has been so becomes quite evident to the investigator making the attempt, for during our entire work there, which extended from January 30 to March 9, 1933, we encountered but 2 days of calm sea. The fact that we were able to work at all times was due to the large size of the Caroline, which has a length over all of 279 feet 10 inches, a beam of 38 feet, depth of hull 27 feet, draft 174 feet, and also to the fact that she carries a 50-ton Sperry gyro-stabilizer, which keeps the yacht al- most on an even keel at all times. Most of the 109 stations covered during our cruise yielded mollusks, many of them members of the family Turritidae. Almost all of the stations were on very rough bottom, and this was particularly true of those in the Mona Island Passage. Probably the most interesting haul was at station 92, which is near the place where the Challenger made her famous haul at her station 24, March 25, 1873. This was one of the four richest hauls made by the Challenger on her whole cruise. Our stations 36, 91, 93, 94, and 95 surround this Chal- lenger station. We have always felt the lack of types or topotypes of the numerous mollusks described by Watson from this station, and our hauls sup- _ plied these. The National Museum is exceedingly rich in West Indian mollusks, having the large collections obtained by government investigators and many specimens acquired through private donations. It is therefore possible with this splendid material to subject our catch to a critical review. The family Turritidae has for some time been a troublesome group whose genera have been variously interpreted by different authors. SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 91, No, 2 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI Most of the difficulties have been due to the fact that authors have been loath to increase the number of genera in the family, which has already 326 generic names to its credit. Also, most authors have lacked the necessary genotypes to fix definitely the characters of each genus. Realizing the confusion that has existed and still exists in the no- menclature of this family, I have been acquiring genotypes of it for the National Museum for some time and can now say that the Museum has specimens of almost all of them, or, where specimens are not available, photographs of them. It is this collection of genotypes that brings to light the woeful inadequacy of names, and in reviewing even as limited a fauna as that here in part discussed, it becomes necessary to add many new names. In the examination of the turritids I find that the nuclear characters here as elsewhere yield useful elements in the definition of groups, but these are points which may be discussed in detail in the final paper, which will give an account of all the mollusks obtained in the Puerto Rican Deep, not merely the new forms here made known. ELDRIDGEA, n. gen. Type species —Eldridgea johnson, new species. Shell moderately large, ovate (early nuclear whorls unknown). The first of the remaining nuclear whorls apparently smooth. The early post-nuclear whorls strongly axially ribbed. Those succeeding marked by expanded foliations that take the place of ribs. These broadly ex- panded elements are best understood by examining the figures (pl. 1, figs. 1-3) ; they suggest the ornamentations of certain Boreotrophons. The outside of the expanded wings, the base, and the columella are marked by more or less equal and equally spaced spiral lirations. The inside of the foliations is smooth. Aperture large. Posterior sinus immediately below the summit; stromboid notch very shallow; inner lip appressed to the columella ; parietal wall covered with a thin callus, which forms a nodule at the posterior angle. This genus suggests Clavus Montfort = Clavicantha Swainson and Tylotia Melville, in which the ribs are spinose or slightly lamellosely expanded, but the present genus carries this to an extreme point. ELDRIDGEA JOHNSONI, n. sp. Plate 1, figs. 1-3 Shell moderately large, ovate, horn-colored, with the inside of the alations and the broad basal band white; interior of aperture porce- laneous with a pinkish tinge. A part of the first turn of the nuclear NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 3 whorl is lost; the remaining nuclear turn appears to be smooth. The early postnuclear whorls are marked by protractively slanting, axial ribs, of which 9 occur upon the first three turns and 10 upon the fourth. On the first three whorls these axial ribs are quite regular, being strongest on the middle of the turns and tapering toward the summit and the periphery. The spaces that separate them here are about as wide as the broad ribs. On the fourth postnuclear whorl they begin to be more oblique and tend toward the formation of a lamina at the tip. This becomes accentuated on the fifth turn, and on the succeeding turns it becomes increasingly more pronounced, gradually forming the broad winglike expansion that characterizes this species. There are 10 ribs on the fifth and sixth, 8 upon the seventh to ninth, and 12 upon the last turn. These alations are marked by incremental lines, and their outside, as well as the base and columella, are crossed by slender, wavy, spiral threads. The insides of the alations are smooth, barring incremental lines. Aperture moderately large and expanded, decidedly channeled anteriorly and at the posterior angle. Outer lip thin, protracted between the posterior channel and slender stromboid notch anteriorly. Inner lip reflected over the somewhat twisted colu- mella as a heavy callus, which extends over the parietal wall and forms a slight lump near the posterior angle. Type——tThe unique type, U.S.N.M. no. 430852, was dredged at station 12, off the north coast of Puerto Rico, in 200 to 300 fathoms between latitude 18°31’ N., longitude 66°00'15” W. and latitude 18° 30'30” N., longitude 66°01’45” W. It has 11.5 whorls remaining and measures: Length, 31 mm; greater diameter, including alations, 19.7 mm. FENIMOREA, n. gen. Type species —Fenimorea janetae, new species. Shell large; nuclear whorls well rounded, smooth. Postnuclear whorls with strong, broad axial ribs that are retractively bent and re- duced in the depressed groove below the summit and extend anteriorly to the fasciole on the base. The finer sculpture on the ribs and inter- costal spaces consists of decidedly wavy incised spiral lines and fine incremental lines, which vary in strength. The combination of these two elements gives to the surface a peculiar effect, resembling the scales on some butterfly wings; this sculpture extends to the basal fasciole. The fasciole itself and the area immediately posterior to it, as well as the rest of the columella, are marked by spiral threads. The aperture is moderately long and broad and strongly channeled an- 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI teriorly. The basal sinus is deep and reflected at the edge with a strong parietal callus; the stromboid notch is shallow. This genus suggests Elaeocyma Dall, type E. empyrosia Dall, but differs from it in having the nuclear whorls rounded instead of cari- nated and the ribs stronger, and above all in the detailed fine sculpture described above. The genus is represented by 11 species in our collection, of which only two have been named, namely Fenimorea moseri, Dall=Pleuro- toma (Drillia) moseri Dall from the West Coast of Florida and Drillia fucata, Reeve from the Bahamas. The unnamed species come from: East Coast of Florida (3) West Coast of Florida (1) Puerto Rico (2, 1 here described) St. Thomas (1) Barbados (2) FENIMOREA JANETAE, n. sp. Plate 1, figs. 4-7 The shell is rather large, with the posterior groove and an area about as wide as this groove, anterior to the groove, on the axial ribs, white. This is followed by a broad zone of chestnut-brown occupy- ing about half the whorls between the summit and suture; this zone terminates a little below the periphery. Anterior to this is a fainter thread of brown and a little paler brown area in the groove just pos- terior to the fasciole. In addition to this, there are, in the lighter bands in the intercostal spaces, indications of pale brown markings. The broad brown band becomes enfeebled on the last portion of the last whorl. The interior of the aperture is bluish white with the dark band shining partly through this, and the callus on the columellar area is porcelaneous. The nuclear whorls are 1.5, small, well rounded and smooth ; the postnuclear whorls are appressed at the summit with a depressed groove occupying the posterior third between the summit and suture, evenly rounded from the anterior termination of this to the periphery, and marked by strong, broad, rounded, axial ribs, which have their strongest development anterior to the sinus at the summit and become attenuated posteriorly in crossing the base, where they extend to the basal fasciole. Of these ribs, 10 are present on the first four whorls, 12 on the fifth to seventh, 14 on the eighth and ninth, and 16 on the tenth. The spaces separating the axial ribs are about as wide as the ribs. In addition to this sculpture the whorls are marked by slender spiral threads in the depressed area near the summit, of NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 5 which 11 are present on the last whorl. Anterior to the depressed area the threads are replaced by pitted impressed lines, which also cover the base. Between the threads and lines, under high magnification, still finer, closely spaced, microscopic spiral striations are present, and and the ribs and the intercostal spaces also bear fine incremental lines with microscopic axial incised lines between them. The heavier incre- mental lines terminating anteriorly in the spiral line of pits divide the space between the spiral lines into scalelike elements suggesting the scales of some butterfly wings, each scale being bordered by a deeper axial depression and marked by microscopic axial striations, as well as the microscopic spiral lines, the axial striations being a little stronger. The columella has a moderately strong basal fasciole, which is bor- dered posteriorly by three feeble spiral threads and crossed by two more, whereas anterior to the basal fasciole the columella bears about six feebly impressed spiral threads. The aperture is moderately large, rather broad, slightly channeled anteriorly with the posterior channel deeply incised and its wall reflected as a strong callus over the parietal wall. The stromboid notch at the anterior end of the outer lip is rather short and shallow; the space between the stromboid notch and the basal channel is clawlike. The parietal wall is covered by a moderately thick callus. There is a stronger varix about a quarter of a turn behind the aperture on the last whorl. Type—vU.S.N.M. no 430249, obtained at station 26 in 33 to 40 fathoms on rough coral rock bottom between latitude 18°30’20” N., longitude 66°22’05” W. and latitude 18°30'30” N., longitude 66°23’ 05” W. It has 12 whorls and measures: Length, 37.8 mm; greater diameter, 14.3 mm. DOUGLASSIA, n. gen. Type species —Douglassia enae, new species. Shell of medium size. Nuclear whorls well rounded, smooth; post- nuclear whorls with a broad concave area immediately below the sum- mit, across which the axial ribs do not extend; the rest convex. Base rather short. Columella short with a feeble fasciole. Aperture rather large, deeply channeled anteriorly and posteriorly, the posterior chan- nel being immediately below the summit; stromboid notch conspicu- ously reflected; columellar wall reflected as a heavy callus; parietal wall with a heavy callus that forms a knob at the posterior angle. The sculpture consists of strong axial ribs that extend from the anterior limit of the concave area, where they are strongest over the base, grow- ing feebler anteriorly. Fine incremental lines are also present on the 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI ribs and in the intercostal spaces. The body of the whorls is marked by fine spiral lirations, while the columella has strong spiral cords. The present genus suggests Symatosyrinx Dall, the type of which is Pleurotoma lunata Lea, which comes from the Yorktown Miocene at Petersburg, Va. It differs from it in having the nuclear whorls well rounded instead of carinated, the columella strongly lirate, the basal fasciole less pronounced, and in being smaller in every way. DOUGLASSIA ENAE, n. sp. Plate 2, figs. 1-3 Shell elongate-conic, wax-yellow with a broad pale-brown band at the periphery. Nuclear whorls 2.5, smooth, forming a pointed apex. The beginning of the postnuclear whorls has the axial riblets char- acteristic of the later postnuclear whorls, but here they are a little more slender and a little more closely approximated. The postnuclear whorls are marked by strong axial ribs that almost form cusps at the anterior termination of the posterior sinal region; they extend only very feebly across the sinal area, which occupies the posterior two fifths of the turns. On the last whorl these ribs are decidedly en- feebled on the base and evanesce at the junction with the columella. Of the axial ribs, 10 occur upon the first six whorls, 12 upon the seventh and the last turn. These ribs are about one third as wide as the spaces that separate them, the latter being broad and concave. In addition to the axial ribs the whorls are marked by rather strong incremental lines that have a decidedly sigmoid curve, being retrac- tively slanting at the posterior sinail region and protractively anterior to this. The spiral sculpture consists of numerous, closely spaced, microscopic obsolete spiral lines. Base moderately well rounded. Col- umella short and stubby, marked by 12 rather strong sinuous spiral threads and finer spiral lines corresponding to those on the spire and base. Aperture moderately large and rather broad, decidedly chan- neled posteriorly and anteriorly with a feeble stromboid notch. The outer lip is protracted between the posterior angle and the stromboid notch into a clawlike element, while the inner lip is reflected over the columella as a heavy callus, which extends over the parietal wall and projects into the aperture at the posterior sinus as a decided knob. There is a heavy varix about one sixth of a turn behind the edge of the outer lip.

It has 6.5 whorls NO. 2 NEW TURRITID MOLLUSKS—BARTSCH if remaining and measures: Length, 16.6 mm; diameter, 6.9 mm. The nucleus was described from one of two specimens, U.S.N.M. no. 430038, obtained at the same station. This specimen has 9 whorls and measures: Length, 11.4 mm; diameter, 4.7 mm. Another lot, U.S.N.M. no. 429205, contains seven specimens from station 104 taken in 80 to 120 fathoms between latitude 18°30'40” N., longitude 66°13'20” W. and latitude 18°30’10” N., longitude 66°13’50” W. In the collection of the United States National Museum is also an undescribed species belonging here, which was labeled Dyillia thea Dall, variety, from the west coast of Florida. FUSISYRINX, n. gen. Type species—Fusisyrinx fenimorei, new species. Shell rather fusus-like in appearance with the aperture almost equal to the rest of the shell and a strong, deeply cut sinus at the summit of the whorls. The columella is slender and but slightly twisted. The nuclear whorls ? . Postnuclear whorls with a few strong knoblike ribs, which extend from the anterior limit of the sutural sinus to the periphery. In addition to this there are strong lines of growth which pass over the ribs and intercostal spaces. The spiral sculpture con- sists of fine spiral threads in the sinus at the summit, succeeded an- teriorly to the sinus by stronger spiral threads, between which finer spiral threads are present. This sculpture is also present on the slender columella, where the finer spiral threads are less numerous. Aper- ture very long, the anterior channel very slender and long, the posterior broad and deeply incised. The outer lip is slender at the edge, and the inner lip appears as a smooth callus and as if the shelly substance carrying the outer sculpture had been here resorbed. This also holds good on the parietal wall of the aperture. FUSISYRINX FENIMOREI, n. sp. Plate 2, figs. 4, 5 Shell very large, of fusus-like shape, milk-white, covered with a very thin translucent periostracum. Nuclear whorls decollated. Post- nuclear whorls strongly rounded, marked by almost knoblike axial ribs, which extend from the anterior limit of the posterior sinus to the periphery. These ribs are almost as wide as the spaces that sepa- rate them. In addition to this the whorls are marked by sigmoid axial lines of growth. Of these ribs, 10 occur upon all but the pen- ultimate and the last whorl, each of which has 12. The spiral sculp- 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI ture consists of fine threads, which in the sinus portion near the summit of the early turns are about as strong as the spiral threads anterior to this, but on the later whorls these spiral threads become less strongly developed, while those anterior to it increase in strength. The anterior portion of the whorls on the later turns are marked by rather coarse, definitely spaced threads, between which finer spiral threads are present, varying in number from one to four. This fine sculpture, combined with the lines of growth, gives a reticulated pat- tern to the spiral grooves between the spiral cords. Base short, well rounded, marked like the anterior portion of the spire. Columella very long, slender, marked by numerous slender, more or less equally spaced spiral threads, which become somewhat enfeebled near the tip. Between these stronger threads an occasional slender spiral thread is present. Aperture tear-shaped with a very long anterior channel. The posterior channel broad and deep, immediately below the sum- mit. The inner lip smooth, appearing as if excavated below the sur- face of the sculptural portion of the shell. — Type —vU.S.N.M. no. 425356, collected at station 35 in 180 to 80 fathoms between latitude 18°23’40” N., longitude 67°16'45” W. and latitude 18°24'45” N., longitude 67°14’15” W. It has eight and one quarter whorls remaining and measures: Length, 71.1 mm; diameter, 20.4 mm. A younger specimen, a topotype, U.S.N.M. no. 430653, has nine whorls remaining and measures: Length, 56 mm; diameter, 16.7 mm. I have seen nothing in our turritid collection that compares with this group. POLYSTIRA Woodring The genus Polystira was created by W. P. Woodring in 1928’ for certain large West Indian turritids. He named the largest of the recent species, generally known as Pleurotoma albida Perry, as type. Unfortunately, the mollusk so designated is not Pleurotoma albida Perry, which Perry states” “is frequently found at New Zealand and Lord Howe’s Island.” Perry’s figure 4, plate 32, of this species does not agree with the West Indian material. It clearly resembles certain shells from North Australia in the collection of the National Museum. The name is, therefore, not applicable to the West Indian shell, which will have to carry the next available designation. * Miocene mollusks from Bowden, Jamaica, pt. 2, p. 145, 1928. * Conchology or the natural history of shells, London, 1811. NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 9 Lamarck in 1816, in his “ Tableau Encyclopedique et Methodique ”, figured on plate 439, as figure 2, the West Indian shell without naming it. Wood, in 1818, in his “ Index Testaceologicus ”’, on page 125, names this species Murex virgo, referring to Lamarck’s figure cited above. This appears to be the oldest available name for the type species. } The type of Polystira Woodring must therefore be Murex virgo Wood= Polystira albida Woodring, not Perry. POLYSTIRA FLORENCAE, n. sp. Plate 3, figs. 4-7 Shell rather large, fusiform, pale brown, excepting the large median keel between summit and suture and a broad area that extends over a little more than half of the posterior part of the columella, which are white. The tops of the other spiral keels are also a trifle paler than the spaces between them. The first 1.5 nuclear whorls are large, well rounded, and smooth. These are followed by about one half of a turn that is crossed by about 10 slightly retractively curved, axial ribs, which are about one fourth as wide as the spaces that separate them. The postnuclear whorls are marked by very strong spiral keels, of which the most conspicuous one is the second one below the sum- mit, which bears the deeply narrow posterior sinus. The first keel occupies the space almost midway between the summit and this keel. Anterior to the strong keel, there are on each whorl two additional keels, one, the stronger, occupying the periphery of the whorls, another a little nearer to the strong second keel than the peripheral and slightly weaker than the peripheral. A slender spiral thread is present midway between the summit and the first, and between the second and third; and two are present between the third and fourth. The spaces between the keels are decidedly concave, and they are crossed by slender, axial riblets, which are retractively curved pos- terior to the strong keel and protractively curved anterior to it. In addition to this the whorls are marked by microscopic lines of growth and spiral striations. The base is short and marked by four keels, which grow consecutively weaker anteriorly. In the middle of the broad spaces between these keels is a slender spiral thread. A con- tinuation of the axial sculpture of the spire is present here. The columella is rather long, slender, and marked by oblique spiral cords, which grow consecutively weaker anteriorly, becoming obsolete to- ward the anterior tip. This also holds good for the continuation of the axial sculpture, which likewise becomes enfeebled and obsolete. TO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. OT Aperture narrow and long, the outer lip deeply incised to form the narrow sinus of the second keel and scalloped by the rest of the keels and cords.

POLYSTIRA MACRA, n. sp. Plate 3, figs. 8, 9, 13, 14 Shell slender, fusiform, pale cream-colored with the columella white. Nuclear whorls almost 2, the first 1.5 rather large, well rounded, smooth, the last half marked by eight slender, not strongly expressed, sinuous, rather distantly spaced, axial riblets. The postnuclear whorls are marked by strong spiral keels, of which the second carrying the sinus, is the strongest. The first is a little nearer to the summit than to the second. The other two keels ornament the anterior half of the whorls, the fourth one being at the periphery and the third midway between this and the strong keel. The spaces between these keels vary in width, that between the first and second being considerably nar- rower than that between the second and third, which equals the space between the third and fourth. All the spaces between the keels are deeply concave. There is a slender crenulated thread at the summit and another slender thread between the first and second spiral keel, a little nearer the second than the first. A feeble spiral thread is present about one fourth of the distance between the second and third keel anterior to the second keel, and a second thread doubly as strong as the last mentioned is a little nearer the third keel than the second. Another spiral thread occupies the space midway between the second and third. The axial sculpture consists of rather strong, NO. 2 NEW TURRITID MOLLUSKS—BARTSCH Il slender, closely spaced, axial riblets, which are retractively slanting posterior to the strong keel and protractive anterior to it. The base is moderately short, well rounded, and marked by four strong spiral cords, which are almost equally spaced, and by the continuations of the axial riblets. A slender thread occurs between the third and fourth. The columella is long and slender and marked by rather regularly spaced spiral threads, which extend to the very tip and which grow gradually weaker from the base anteriorly. The axial sculpture on the base is almost as strong as on the spire, while on the colu- mella it becomes decidedly weakened and evanescent toward the tip. Aperture narrow, slender, with a deep narrow sinus on the outer lip corresponding to the second keel. The rest of the outer lip is rendered more or less sinuous by the external sculpture.

Nuclear whorls 1.7, the first smooth and well rounded, the second one with a faint submedian angulation. Postnuclear whorls well rounded, bearing a series of nodulelike ribs, I2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI which are almost median on the whorls and evanesce at the sutural sulcus and on the anterior portion of the whorls. These nodules are cusped on the early turns and become broad and well rounded on the later whorls. Of these nodules, 12 occur upon the first four post- nuclear turns, 14 upon the fifth to eighth, 16 upon the ninth, 20 upon the tenth to twelfth, and 25 on the last whorl. In addition to these axial nodules the whorls are marked by closely spaced, slender, sig- moid lines of growth, which have a retractive curve in the sinus at the summit and are protractive anteriorly. The spiral sculpture on the early postnuclear whorls is almost absent, at best merely indicated, but beginning with the fourth whorl and from there on it increases steadily in strength, eventually forming in the sinus at the summit a series of low, flattened cords of which 18 are present between the summit and the anterior termination of the sinus, those near the sum- mit being more broadly and more strongly developed than those on the anterior portion. Anterior to the sinus the whorls are marked by rather wavy subequal and subequally spaced, somewhat flattened spiral threads of which 20 are present on the last whorl. Suture slightly constricted. Periphery well rounded. Base short, well rounded, marked like the spire with 10 spiral cords, which equal those on the spire in strength and spacing.

FUSITURRICULA ENAE, n. sp. Plate 3, figs. 1, 2, 10 Shell of medium size, fusiform, pale horn-colored, with the inter- costal spaces pale chestnut-brown, and with a pale chestnut-brown median basal band, and the tip of the columella of the same color Nuclear whorls 1.5, smooth, well rounded. A few closely spaced wrinkles mark the transition of the nuclear turns to the postnuclear whorls. Postnuclear whorls moderately high. The first bears a strong median nodulose cord. On the second this cord tends to split and from there on develops into two nodulose cords, the nodules repre- senting the axial ribs. The nodules on the first postnuclear whorl are cusplike, whereas those of the succeeding turns become increasingly more rounded and elongated, their long axes corresponding with the spiral sculpture. Of these nodules, 10 occur upon the first and second turn, 12 upon the third and fourth, 14 upon the fifth and sixth, and 16 upon the seventh and last turns. Anterior to the two nodulose spiral cords the whorls are marked by four almost equal and equally spaced spiral cords. Periphery and base well rounded. The latter is marked by five equal and equally spaced spiral threads. The entire base and the anterior portion of the whorls are in addition crossed by rather coarse lines of growth, which are particularly emphasized between the spiral cords.

GLYPHOSTOMA (GLYPHOSTOMA) EPICASTA, n. sp. Plate 4, figs. 4, 7, 9 Shell rather large, elongate-conic, milk-white. Nuclear whorls almost 3, the first one well rounded, the other two with a strong submedian keel. Postnuclear whorls rather low, well rounded, marked by axial ribs that evanesce in the sulcus below the summit, and on the last whorls evanesce as they pass over the base. Of these ribs, 10 occur upon the first four, 12 upon the fifth and sixth, 14 upon the seventh and eighth, 18 upon the ninth, and 20 upon the last turn. In addition to the axial ribs the entire surface of the shell is well marked by lines of growth, which on the sulcus below the summit are strength- ened to form a series of wrinkles more numerous than the axial ribs. The spiral sculpture consists of well-developed cords, which are slightly flattened and which are about one third as wide as the spaces that separate them. The intersection of the axial ribs and spiral cords is rendered nodulose, the long axes of the nodules coinciding with the spiral sculpture. Of these spiral cords, one is present on the first turn, two on the second to sixth, three on the seventh, and seven on the remaining. Beginning with the eighth whorl, finer spiral threads are apparent in the sulcus below the suture, and these increase in number with the turns. On the last turn there are six. Suture moderately constricted. Periphery well rounded. Base rather long, well rounded, marked like the posterior portion of the last whorl, five spiral threads being present. Columella rather long, marked by lines of growth and 11 spiral threads, which become consecutively a little less strong from the posterior anteriorly. The entire surface of the shell is rather coarsely granulatedly sculptured. Aperture rather long, decidedly channeled posteriorly and anteriorly. Outer lip reinforced by a strong varix a little beyond the edge, the portion of the lip between the varix and edge being reflected over the aperture as a clawlike element.

GLYPHOSTOMA (GLYPHOSTOMA) ELSAE, n. sp. Plate 4, figs. 1, 3, 6 Shell broadly conic, yellowish white, with the tip horn-colored and the spiral cords of the postnuclear whorls pale chestnut-brown, fading as they cross the ribs. On the base the spiral cords are.interrupted by the much more numerous ribs, which gives them a catenated effect. The tip of the base is brown for about one fifth of its length, but an area of equal width posterior to this lacks the brown inter- rupted bands. The interior of the aperture is bluish white. Nuclear whorls three, the first well rounded, the other two marked by a strong acute spiral keel a little anterior to the middle of the whorls. Postnuclear whorls well rounded, marked by exceedingly strong, broad, almost humplike axial ribs, which become very attenuated in the posterior sinal region and evanesce at the suture. Of these ribs, to occur upon all but the last whorl, which has 12. The intercostal spaces are a little wider than the ribs. At the summit of the whorls in the posterior sinal region the shell is marked by rather strong, closely spaced, curved riblets, which give to this part a crenulated aspect. On the base additional riblets are intercalated so that one, two, or even three slender axial ribs may appear between the heavy knobs described above. These are of very regular strength and spacing and are rendered nodulose by the spiral threads. The yellowish white nodules furnish a decided contrast to the dark areas that separate 2 16 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI them. The spiral sculpture of the postnuclear whorls consists of three exceedingly feeble threads in the sinal region at the summit on the first two turns. On the third turn an additional thread is added and on the remaining turns, two more. The posterior of these threads render the later whorls finely nodulose. Anterior to the sinal groove three spiral threads are present on the first and second of the postnuclear whorls, and five on the remaining whorls except the last, which has six. Here too an additional slender spiral thread is present between the first and second and the second and third of the strong threads. The suture is given a somewhat false aspect by the appressing of the sum- mit of the whorls against the preceding turn. Periphery well rounded. Base moderately long, marked by the slender axial riblets described above, which become evanescent a little anterior to the middle, and 21 spiral threads, which are of almost equal strength and spacing, the last three near the tip of the columella, however, being less strong and a little more closely spaced. The entire surface of the shell is ' covered with fine granules. Aperture moderately large and rather broad, strongly channeled anteriorly and posteriorly. Outer lip re- inforced by a strong varix, from which the edge of the lip projects as a clawlike element that is bent inward. The callus on the inside of the lip marking the varix is finely denticulated. Fine denticles also mark the somewhat sinuous columellar margin of the aperture.

GLYPHOSTOMA (GLYPHOSTOMA) HERMINEA, n. sp. Plate 4, figs. 2, 5, 8 Shell elongate-comc, rather broad, yellowish white. Nucleus decol- lated. Early postnuclear whorls somewhat worn, those remaining marked by broad, stout, slightly retractively slanting axial ribs, which are about as wide as the spaces that separate them and which evanesce at the sulcus immediately below the summit and likewise gradually evanesce on the base. Of these ribs, 10 occur upon the first to third and 12 on the remaining turns. On the sinus below the summit the axial sculpture consists of numerous rather closely spaced curved riblets, which render this part slightly crenulated. The spiral sculpture consists of rather strongly developed, somewhat flattened cords, which in NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 17 passing over the axial ribs render these nodulose, the long axes of the nodules coinciding with the spiral sculpture. Of these spiral cords, two occur on the third and fourth, four on the fifth, five on the sixth, and six on the last whorl between the summit and the periphery. In addition to this there are fine spiral threads on the channel, at the summit of which three occur on the fifth, four on the sixth, and five on the last whorl. On this there are also some finer spiral threads between some of the spiral cords. Suture well constricted. Periphery well rounded. Base moderately long, marked by the continuation of axial ribs and six spiral cords. Columella moderately long, marked in the posterior half by the feeble continuation of the axial ribs and 11 spiral threads, which grow consecutively weaker from the posterior anteri- orly. In addition to this the entire surface of the shell is marked by fine lines of growth and densely placed granulations. Aperture moderately long, decidedly channeled both anteriorly and posteriorly. Outer lip reinforced by a strong callus a little behind the edge, the edge being produced into a clawlike element. The inside of the callus within the aperture bears seven strong denticles. Inner lip also denticulated, the denticles not so strongly developed as on the outer lip. The anterior portion of the inner lip is abraded so that the actual count of the denticles cannot be made. Parietal wall covered by a callus that is developed into a strong denticle opposite the posterior termination of the callus of the outer lip, which renders the posterior sinus almost tubular. Type—The unique type, U.S.N.M. no. 430354, was collected at station 102 in 90 to 500 fathoms between latitude 18°50’30” N., longitude 64°43’ W. and latitude 18°51’ N., longitude 64°33’ W.

Postnuclear whorls moderately well rounded, marked by somewhat sinuous, retractively slanting axial ribs, of which 12 occur upon the first, second, and third, 14 upon the fourth, 16 upon the fifth, 18 upon the sixth, and 20 upon the last whorl. These ribs become somewhat attenuated on the shoulder near the summit, where they are somewhat bent to correspond to the posterior channel. In addition to this the whorls are marked by rather strong spiral cords, of which one occurs upon the first, two upon the second and third, three upon the fourth, and four upon the remaining turns excepting the last, which has five. These cords are of about equal strength, and the first of them is about one fourth the distance between the sum- mit and suture anterior to the summit. The intersection of the axial ribs and spiral cords form elongate nodules having their long axes parallel to the spiral cords. In addition to this the entire surface of the axial ribs and intercostal spaces are marked by lines of growth. Suture moderately constricted. Periphery well rounded. Base mod- erately long, marked like the spire, bearing four nodulose cords. Colu- mella rather long, moderately stout, marked by 17 spiral cords and threads, which grow progressively weaker anteriorly, the last six being very feebly indicated. Aperture rather large, outer lip with a very strong varix a little behind its edge, from which a clawlike element projects into the aperture, bearing the external sculpture on its outer surface. This structure, together with a rather strong denticle on the parietal wall, gives to the posterior channel an almost tubular effect. Inner lip covered with a thick callus, which is reflected over the columella and the parietal wall.

Nuclear whorls a little more than three, the first well rounded, the second with a very feeble angu- lation, and the third with a submedian carina. Postnuclear whorls marked by 10 irregularly developed, protractively slanting axial ribs, which evanesce in the sinus at the summit and at the periphery. These irregular callus-like ribs are about one third as wide as the spaces that separate them. In addition to this axial sculpture the whorls are NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 19 marked by fine lines of growth. The spiral sculpture consists of a raised, slightly submedian cord on the first turn, which at its junction with the axial ribs renders this sharply nodulose. This keel has a tendency to bifurcation, which becomes complete on the next turn, where two nodules are present, and on the last turn an additional nodule appears on the periphery. In addition to these spiral cords the entire surface of spire and base is marked by closely spaced microscopic spiral striations. Suture moderately constricted. Periphery well rounded. Base moderately long, marked by a feeble spiral thread below the periphery and another near the columella. The columella is slender and marked by eight poorly expressed spiral threads. The aperture in the only specimen at hand is fractured. I am therefore unable to give a description of the features covering this part of the shell. The inner lip is decidedly sigmoid.

It is also distantly related to Glyphostoma (Glyphostomops) hendersoni. COMPSODRILLIA PETERSONTI, n. sp. Plate 5, figs. 6, 7, 9 Shell very elongate-conic, bluish white. Nuclear whorls 2.5, the first two well rounded, smooth, the last half crossed by a number of distantly spaced axial riblets. Postnuclear whorls well rounded, the first with two nodulose spiral threads, the second with three, of which the median is the strongest. These remain throughout the length of the shell. In addition to this the appressed summit of the shell appears as a spiral cord. The posterior sinus is narrow and located immedi- ately below the spiral cord at the summit. In addition to the strong spiral cords finer spiral threads are present both in the sinal sulcus near the summit and on and between the ribs anterior to this. In ad- dition to the spiral sculpture the whorls are marked by axial ribs which have their beginning in the nodulose spiral threads on the first postnuclear whorl. These axial ribs are slightly protractively slanting. They extend but very slightly posteriorly to the posterior sulcus, and evanesce anteriorly on the base of the last whorl. They are more than twice the width of the spaces that separate them. Of these, Io occur upon the first to seventh, 12 upon the eighth to tenth, and 14 740) SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI upon the last whorl. These ribs and the spaces that separate them are marked by lines of growth, which also extend across the posterior sulcus and over the base and columella and give to the general sur- face a finely reticulated clothlike sculpture. Suture slightly impressed. Base well rounded, marked by four strong nodulose spiral cords like the spire and the intervening spiral threads. Columella rather long, twisted, with an obscure indication of an umbilicus at its tip, marked by seven strong, broad, rounded, very nodulose spiral cords, and six slender threads on the anterior tip. Between and on the strong cords on the columella finer threads are present. Aperture rather long, strongly channeled anteriorly and posteriorly, the posterior chan- nel almost forming a tube, since the outer lip and the parietal callus bend forward, partly closing it. The outer lip bears a strong varix one fifth of a turn behind its edge, and beyond this is drawn into a clawlike element, which bends in very slightly toward the aperture. The inner lip is strongly developed and projects considerably beyond the columella and extends as a rather thickened callus over the parietal wall, forming a decided knob at the termination of the posterior angle of the aperture.

Plate 6, figs. 6-8 Shell elongate-conic, covered with a very pale, ashy, dehiscent peri- ostracum, which in the type is absent on the base and columella and gives the shell a decidedly bicolored effect, the shell itself appearing white. Nuclear whorls 2.5, well rounded, smooth, the last half crossed by a small number of axial riblets. First postnuclear whorl with two nodulose spiral cords. On the next turn these split into two and three NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 21 tuberculated cords, the third one almost falling into the suture, being appressed to the cord at the summit of the succeeding turns. These remain inconspicuous on the succeeding turns, while the other two occupying the middle portion of the shell become decidedly pro- nounced. The cord at the summit forms an abrupt sloping shoulder, and the space between this and the first strong spiral cord constitutes the sulcus marking the posterior channel of the shell. In addition to these spiral cords the cords themselves and the spaces that separate them are marked by strong spiral threads. This is also true of the sulcus at the summit, the base, and partly so of the columella. The axial sculpture consists of very heavy, broad, low, rounded ribs which are about twice as wide as the spaces that separate them. These ribs are rendered nodulose by the two strong spiral cords. They are also marked, as well as the intercostal spaces, by slender lines of growth that extend over the entire surface of the shell. Of these ribs, 12 are present on all the whorls. Suture slightly constricted. Periphery well rounded. Base short, marked by three strong spiral cords. Colu- mella moderately long, slightly curved and marked by nine strong spiral cords, between and on which slender spiral threads are present. Aperture moderately long, channeled posteriorly and anteriorly. Un- fortunately, the outer lip is fractured in the unique type so that it is impossible accurately to describe this, and the shell is not sufficiently mature to have differentiated the heavy varix behind the aperture characteristic of the group. The inner lip constitutes the heavy callus that extends upon the parietal wall. Type.—tThe type, U.S.N.M. no. 429401, has 11.7 whorls and mea- sures: Length, 26.6 mm; diameter, 7.4 mm. It was dredged at station 67 in 180 to 280 fathoms between latitude 18°30’12” N., longitude 65°45/48” W. and latitude 18°32'18” N., longitude 65°46’12” W. This species is easily differentiated from Compsodrillia tristicha by the fact that only two of the strong spiral keels are apparent on the whorls. COMPSODRILLIA NANA, n. sp. Plate 6, figs. 1-3 Shell small, elongate-conic, yellowish white. The first one-half nu- clear turn well rounded, smooth, the last half marked by a few rather distantly spaced, slightly protractively slanting axial riblets. Post- nuclear whorls well rounded, the first marked by three slender spiral cords, of which the anterior two increase more rapidly in size than the first one, which remains rather feeble. The summit of the whorls is 22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI marked by a smooth spiral cord representing the portion appressed to the preceding turn. On the later whorls the sinal sulcus at the sum- mit is crossed by two slender spiral threads anterior to the cord at the summit which divides the space between this cord and the first strong nodulose cord into nearly equal portions. There is also a slender spiral cord between the first and second strong nodulose cords on the antepenultimate turn and two on the last whorl. There are two slender spiral cords between the second nodulose cord and the nodulose cord at the periphery which shows weakly in the suture of the whorls. The axial sculpture consists of strong, broad, rounded, protractively slanting ribs, which are about twice as wide as the spaces that separate them. The junction of these ribs with the stronger spiral cords produces nodules. Suture well impressed. Periphery marked by a nodulose spiral cord, the major portion of which, how- ever, falls immediately below the periphery. Base short, well rounded, marked by two nodulose spiral cords. Columella rather short and stumpy, marked by nine subequal, closely spaced, feebly nodulose spiral cords. Aperture rather short, decidedly channeled anteriorly and posteriorly, the posterior channel falling in the posterior angle of the aperture. There is a strong varix a little behind the edge of the outer lip, and the outer lip between the channel at the summit and its base is protracted into a clawlike element, which, however, does not infringe upon the aperture. The inner lip is reflected as a distinct wall upon the columella and forms a heavy callus on the parietal wall. Type—uvU.S.N.M. no. 430562, collected at station 13 in 200 to 300 fathoms between latitude 18°31'05” N., longitude 66°02’15” W. and latitude 18°30’30” N., longitude 66°04’05” W. It has 7.5 whorls and measures: Length, 8.7 mm; diameter, 3.1 mm. DARBYA, n. gen. Type species —Darbya lira, new species. Shell elongate-conic. Nuclear whorls well rounded, smooth. The early postnuclear whorls with a single median row of cusps, the later ones with heavy knoblike axial ribs anterior to the sulcus at the sum- mit, which are crossed by strongly developed, low, well-rounded, weakly nodulose, spiral cords anterior to the sulcus. The entire sur- face is marked by fine lines of growth, which are retractively slanting in the sulcus and protractively slanting on the rest of the turn. Suture strongly appressed. Base well rounded. Columella short, thickened to form a broad fold opposite the varix of the outer lip; this fold is separated from the parietal wall by a deep concave channel. The NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 23 outside of the columella is marked by a few strong spiral cords. Aper- ture very strongly channeled posteriorly and anteriorly. The posterior channel falls immediately below the summit and is deeply incised. A strong varix is present about half a turn behind the edge of the outer lip which is protracted to form a clawlike element anterior to the sinus. The inner lip appears as a heavy callus, which is reflected over the columella and extends up on the parietal wall. DARBYA LIRA, n. sp. Plate 6, figs. 4, 5; plate 7, figs. 6, 8 Shell elongate-conic, pale yellow, with a faint brown band encircling the whorls a little anterior to the sinal sulcus at the summit. Nuclear whorls 1.5, smooth, well rounded. Postnuclear whorls well rounded, marked on the first three turns by a submedian row of distantly spaced cusps. On the succeeding whorls these cusps become elongated into ribs that extend from the sinal sulcus at the summit anteriorly to the suture, becoming weaker toward the suture. Of these ribs, 10 occur upon the first whorl, 12 upon the second and third, and 14 upon the remaining whorls except the last, which has 16. The spaces that sepa- rate these ribs are a little less wide than the ribs. In addition to this there are numerous fine lines of growth, which slope retractively in the sulcus at the summit and protractively anteriorly. The sulcus at the summit is without spiral sculpture, whereas in the region anterior to it both ribs and intercostal spaces are crossed by rather strong, low, rounded, spiral cords, of which four occur upon the fifth to seventh, five upon the eighth, seven upon the ninth, and eight upon the last ‘whorl between the summit and suture. These spiral cords are more or less equal. Suture rendered conspicuous by the slightly sloping shoulder of the summit of the whorls. Periphery well rounded. Base short, marked by the feeble continuation of the axial ribs and by seven spiral cords which are of unequal strength. Columella short and stubby with a strong, broad fold opposite the varix on the outer lip which is separated from the parietal wall by a concave groove; marked by seven rather broad spiral cords, which are separated by narrow channels. Aperture short, decidedly channeled anteriorly and posteriorly, the posterior channel being deeply notched and at the summit of the shell. There is a broad varix half a whorl behind the aperture, the outer lip being protracted between the sinus and the basal portion. The inner lip is appressed to the columella as a heavy callus which extends over the parietal wall. 24 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.

LEPTODRILLIA SPLENDIDA, n. sp. Plates7, figss 2.5, 7 Shell small, elongate-conic, shiny. Nuclear whorls 1.5, well rounded, smooth. Postnuclear whorls moderately well rounded with strongly developed axial ribs, which begin weakly at the summit of the whorls and become strongest at about the anterior termination of the pos- terior third, again gradually weakening on the base and evanescing on the columella. These ribs on the early whorls are cusped at their highest elevation. On the later whorls the cusps become less pro- nounced. Ten occur upon all but the last whorl, which has twelve. There is a very strong varix a little distance behind the outer lip. The lines of growth are exceedingly fine, and the spiral sculpture is absent on all but the columella, thus giving to the entire surface of the shell a decidedly glassy appearance. On the anterior two thirds of the colu- mella nine slender spiral threads are present. Aperture rather broad, decidedly channeled anteriorly and posteriorly. The posterior chan- nel is at the summit of the whorl and is deeply incised. The outer lip from the channel to the slender notch anteriorly is protracted into a clawlike element. Inner lip appressed to the columella as a heavy cal- lus that extends over the parietal wall and forms a decided knob over the posterior angle.

Plate 7. figs. 1, 3,4 Shell small, elongate-conic, vitreous, semitranslucent. Nuclear whorls 1.5, well rounded, smooth. Postnuclear whorls moderately well rounded, marked by rather strong, almost vertical axial ribs, which become weak toward the summit and which attain their largest development on the posterior third of the whorls. On the first post- nuclear whorl these ribs are cusped; on the later ones they become less elevated. On the last whorl they extend but feebly across the base and evanesce on the columella. These ribs are about two thirds as wide as the spaces that separate them. Eight are present on the first, and 10 on all but the last whorl, which has 12. In addition to the axial ribs the whorls are marked by fine incremental lines on the spire as well as the base. Suture well impressed. Periphery well rounded. Base moderately long, well rounded. Spiral sculpture is absent on the spire and base and present on the short, stout columella, which is crossed by nine spiral threads. Aperture rather large, strongly channeled anteriorly and posteriorly. The posterior sinus is deeply notched and immediately below the summit. There is a slender strom- boid notch a little posterior to the anterior termination of the outer lip. The space between this and the posterior sinus is protracted into a clawlike element. The inner lip is appressed to the columella as a callus which extends up over the parietal wall, where it develops into a conspicuous nodule near the posterior angle.

In 1928 Dr. Woodring described the genus Syntomodrillia,’ citing Drillia lissotropis Dall as type.

Range of temperatures, 54°.5 to 71° F. Mr. Watson’s specimen is not sufficiently perfect to decide with certainty, but it looks very much like the present species. The examination of better material since the first description was made shows this species to have the regular Drillia aperture and nucleus, and it is therefore referred to that genus. The curvature and number of the ribs vary slightly, and the spaces between are indifferently perfectly smooth, or finely spirally striate, especially toward the anterior end of the shell. .... These shells are so very small and polished that it is extremely difficult for an artist in pure line-work to represent them adequately. Only lithography with its delicate mutations of shade can do it properly. For this reason our figures of this species are less satisfactory than most of these which represent rougher and larger shells. Critically examining the material in the collection of the United States National Museum, I find that Dr. Dall in his last report em- braced three species under this name, one belonging to the genus Leptadrillia Woodring, another to Syntomodrillia Woodring, and a third to an unnamed genus. Woodring, in selecting a specimen for his genotype, unfortunately chose the specimen having the “ spiral sculp- ture consisting of fine threads on pillar and of microscopic threads between ribs of later whorls,’ (Woodring), which applies not to Dril- lia lissotropis Dall as defined in 1881, but to Drillia lissotropis Dall in part, as emended by him in 1889. It is the Drillia lissotropis Wood- ring 1928, an undescribed species, which I now call Syntomodrillia qwoodringt. NO. 2 NEW TURRITID MOLLUSKS—BARTSCH 27 SYNTOMODRILLIA WOODRINGI, n. sp.

Nuclear whorls 2.5, smooth, well rounded; the early postnuclear whorls marked by almost nodulose axial ribs, which are largest posterior to the periphery and give to these whorls a somewhat crenulated aspect. These ribs gradually grow longer on the succeeding turns, and on the last turn they extend over the base to the columella. They are strongest on the middle of the shell and become less strong anteriorly. There are 10 on the first and second postnuclear whorls, 12 on the third to sixth, and 16 upon the last. On the last whorl there is a decided hump a little behind the aperture. The spaces separating the axial ribs are about as wide as the ribs, or a little wider. They are crossed on the spire by slender, spiral threads, which are confined to the anterior two thirds of the turns between the summit and the suture. Of these, six occur upon the fourth, seven upon the fifth and last whorl between the summit and the periphery, and eight between the periphery and the insertion of the columella on the well-rounded base. The columella is of moderate length crossed by nine almost equal spiral threads, which are much stronger than those on the base. Aperture moderately long and rather broad, decidedly channeled at the posterior angle of the aperture and also anteriorly ; outer lip thin, decidedly channeled at the posterior angle, and protracted between the channel and its anterior limitation; inner lip reflected over and appressed to the columella as a thick callus that extends up over the parietal wall, where it forms a lump near the posterior angle of the aperture. - Type—vU.S.N.M. no. 87477c, dredged by the Blake at station 273 in 103 fathoms off Barbados.

Milne Edwards and later described in detail and figured by Milne Edwards and Bouvier. Of C. agassizui, these authors recognized one varietal specimen from off Havana; the first Johnson-Smithsonian Deep-Sea Expedition obtained three similar specimens in Puerto Rican waters. This additional material permits establishing that so-called variety as a distinct species, to which the name bouvieri is here given. Family DORIPPIDAE Dana Genus CYCLODORIPPE A.

Description —Cyclodorippe bouvieri differs from C. agassizii as follows: There is no spine on the protogastric regions; the median spines are tubular, not conical, and are higher than in agassizi; the granulation is coarser on carapace and cheliped; the margin of the rostrum is arcuate, not angled; orbit narrow in dorsal view, margin rounding, orbital spine smaller than in the allied form. Wrist with a prominent blunt outer tooth or spine near distal end and directed forward. Type locality and distribution.—A male specimen from station 100, northeast of Puerto Rico, latitude 18°40'15” N., longitude 64°50'15” W., 150 fathoms, March 4, 1933, has been selected as the holotype (U.S.N.M. no. 67827). It has a carapace length of 5.2 mm and a width of 5.6 mm. An ovigerous female was also taken in the same haul. A second male specimen was taken at station 1o1, latitude 18°45/40” N., longitude 64°48’ W., in 300 fathoms. The specimen that Milne Edwards and Bouvier thought represented but a variety of C. agassizii was dredged by the United States Coast Survey steamer Blake off Havana, Cuba (station 53) in 242 fathoms.

Plate 1, figs. 1, 2: plate Bie hikers pl Locality —Caroline station 102; northeast of Puerto Rico (lat. 18°51’ N., long. 64°32’ W.); 90 to 500 fathoms; March 4, 1933. Three specimens (U.S.N.M. nos. E.3121 [type], E.3122, and E.3123). Description.—The centrodorsal (pl. 1, figs. 1, 2) is sharply conical, the sides in profile straight in the proximal two thirds, thence very gradually and slightly turning outward and running to the pointed tip, longer than broad, 2.7 mm wide at the base and 3.5 mm long, measured along the sides interradially. The cirrus sockets are closely crowded all around the centrodorsal, which shows no trace of division into radial areas. There are proximally three columns of cirrus sockets in each radial area; the two outer columns of cirrus sockets consist of usually nine sockets, which diminish gradually in size from the base to the tip. The median column is incomplete, consisting of three or four sockets only and ending slightly beyond the middle of the centrodorsal. | The cirri are lacking. The ends of the basal rays are indicated by low, broad, and incon- spicuous tubercles in the interradial angles of the calyx. SMITHSONIAN MISCELLANEOUS COiLECTIONS, VOL. 91, No. 4 to SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI The radials are visible as curved bands with parallel sides from six to eight times as broad as long just above the centrodorsal. The anterolateral angles of adjacent radials are separated by a slight notch, the sides of which make an angle of about 90° with each other. There are no subradial clefts, but the line of junction between the centro- dorsal and the radials is slightly and narrowly incised. The IBr, are about three times as broad as their lateral length, with the lateral edges, as viewed dorsally, approximately straight and parallel and separated from those of their neighbors by a narrow interval. The proximal border is straight, but the distal is deeply incised in the median portion by the backward projection of the axillary, which reaches a point between one third and one half the distance from the distal to the proximal edge. The [Br, (axillaries) _ are longer than broad, and are more or less rhombic in shape. The proximal sides are rather strongly concave, and the distal sides are broadly S-shaped, curving inward from the lateral angles and thence gradually outward, becoming almost parallel on the sides of the un- usually produced anterior angle, which is broadly truncated. The first brachials are at least four times as long exteriorly as interiorly. The proximal border is broadly S-shaped, following the curve of the adjoining border of the axillary. The distal border runs inward from the outer anterolateral angle approximately at right angles to the longitudinal axis of the arm to a point somewhat beyond the midradial line, then curves outward and runs at a very slight angle to the proximal border to the inner anterolateral angle. The second brachials are larger than the first, and are irregularly quadrate with their lower angle rather deeply incising the first brachial. The third brachials (the hypozygals of the first syzygial pair) are low triangular, the inner border being about twice as long as the median length and the outer border being reduced almost or quite to a point. The arms are not preserved beyond this point. The width of the animal at the level of the third brachials is about 6.5 mm. \ second specimen from the same locality resembles the first, but is very slightly smaller. In a third specimen from the same locality (pl. 2, fig. 4) the cirri are 10.0 mm long with 27 segments, of which the first is from twice as broad as long to about as long as broad, the second is about as long as broad or slightly longer than broad, the third is about three times as long as the median width, the fourth is still longer, and the fifth 4 NO. 4 TWO NEW CRINOIDS—CLARK oS) and sixth are five or six times as long as the median width; those following decrease in length so that the last 12 are only about one third again as long as broad. The elongate earlier segments have expanded ends, the distal end being somewhat produced, especially dorsally, and slightly overlapping the base of the segments following. On the short and more compressed distal segments the production of the distal edge dorsally becomes narrowed and accentuated so that the dorsal profile of the outer portion of the cirri is strongly serrate, whereas the ventral profile.is smooth. The opposing spine is triangu- lar, erect, arising from the entire dorsal surface of the penultimate segment, equal to half the width of the segment in height, and much higher than the production of the distal edge of the segments pre- ceding. The terminal claw is small, conical, and scarcely curved. P, is 4.4 mm long with 17 segments and is slender and evenly tapering. The first three segments are about as long as broad, and those following slowly increase in length so that the seventh is about twice. as long as broad, the tenth is about three times as long as the median width, and the outermost are about four times as long as the median width. From the tenth onward the segments are constricted centrally, and the slightly projecting distal edge is finely spinous dorsally. P, is 4.3 mm long with 12 segments, of which the first is about as long as broad, the second is about one third again as long as broad, the third is somewhat more than twice as long as broad, and those following are greatly elongated with slightly produced and very finely spinous distal ends. The pinnule is about as stout basally as P, but tapers rather more rapidly, the distal half being very slender, though not flagellate. P,; resembles P, and is about the same length or slightly shorter, with about 10 segments. It is about as stout basally as P. but tapers more gradually and evenly, so that it appears stouter in the proximal half. It bears a gonad which extends from the middle of the fourth to the end of the proximal third of the sixth segment. The next three pinnules are similar to Ps. The distal pinnules are 6.0 mm long with 17 segments, which, except for the first two, are much elongated and very slender. Remarks —No species of the genus Psathyrometra has heretofore been known from the Atlantic. It is represented in the Indian and Pacific Oceans by 14 species, which range from the eastern coast of India to the Lesser Sunda, Philippine, and Hawaiian Islands, thence northward to the northern part of the Sea of Japan and the Aleutian 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. YI Islands, and southward along the coast of North America to Panama and the Galapagos Islands, in from 184 to 1,617 fathoms of water. The new species, P. acuta, appears to be most closely related to P. major and P. mira, which are found on the western coast of the Malay Peninsula and southward to the Lesser Sunda Islands in 185 to 434 fathoms of water. These agree with P. acuta in having two anda partial third column of cirrus sockets in each radial area on the centrodorsal, but in both of them the radial areas on the centrodorsal are conspicuously delimited by broad grooves or bare lines. DIPLOCRINUS CAROLINAE, n. sp. Plate 1, fig. 3; plate 2) hes Locality.—Caroline station 47 ; west of Puerto Rico (lat. 18°17’05” N., long. 67°24’45” W.); 280 to 340 fathoms; February 13, 1933. One specimen (U.S.N.M. no. E.3124 [type] ). Description.—The stem as preserved is 47 mm long and, in section, is pentagonal with broadly rounded angles. There are seven complete internodes, six of five and one of six columnals. The columnals alternate thick and thin, the thick ones being twice as high as the thin ones or even higher, and some of the thin ones being incomplete. The cirri are about 25 mm in length and consist of 26 to 29 seg- ments, of which the first 6 have a single dorsal tubercle and those following have two dorsal tubercles, a proximal and a distal, with often a small tubercle between them. The penultimate segment is entirely smooth dorsally. The terminal claw is short, stout, and strongly curved. There are exactly 30 arms, which are about 75 mm long from the radials. Each post-radial series bears two IIBr series, and each of these bears externally a II[IBr series, so that the arms on each post- radial series are six, arranged in 2,1,1,2 order. The division series are only slightly rounded dorsally and have broadly and sharply flat- tened sides so that the basal portion of the crown is very compact. Remarks.—This new species is closely related to D. maclearanus (Wyville Thomson), which was dredged by the Challenger off Barra Grande, south of Pernambuco, Brazil (Jat. 9°05’ S., long. 34°50’ W.), in 350 fathoms on September 10, 1873, from which it differs in having a larger number of internodals, in having more segments in the cirri, and in having the cirri provided with prominent dorsal tubercles.

Description.—Diplotriaena: Body long, slender, attenuated at ex- tremities, more abruptly so at anterior than at posterior portion. Oral opening more or less oval in shape, not surrounded by lips. Four pairs of large submedian cephalic papillae, one papilla of each pair internal to the other papilla; papillae approximately equal in size. Lateral papillae or amphids appearing as dark areas, one on each lateral side, situated between the two outer submedian papillae. Chitinous tridents (fig. 1, b) very conspicuous, one on each lateral side of anterior end of esophagus, their distal ends somewhat enlarged and tips of dorsal and ventral prongs of tridents delaminated. Esophagus differentiated into an anterior short, narrow, and a posterior long, broad portion. Intestine usually visible through body wall as a narrow dark streak extending through most of body length. Male 33 mm long by 390 » wide near equator of body.

D. serratospicula may be distinguished from all other species of the genus Diplotriaena, so far as the present writer is able to determine from the published descriptions and figures of those species, by the short spicule which is serrated for its entire length except for the two extremities, and by the size of the long spicule, which is nearly two and one half times as long as the short spicule. This long spicule is exceeded in length by those of only two other species of the genus, namely, D. nochti Hoeppli and Hstt (1929) and D. obtuso-caudata (Rudolphi, 1819). LITERATURE GITED Hoepput, R.

While on this cruise to Puerto Rico and adjacent areas, a few birds were taken and examined for parasites; these included a pelican (Pelecanus occidentalis occidentalis), a booby (Sula leucogastra), and a duck (Nyroca affinis). From these hosts were collected five species of trematodes that appear to be new, the preliminary descriptions of which are given in this paper. A more extended discussion of these forms will appear in a later paper dealing with all of the parasitic worms collected by the expedition.

Uterus long, extending posteriorly in a series of short transverse loops to near posterior end of body, where it turns and extends anteriorly in a similar manner, passing between testes and between testes and ovary to its termination in the genital sinus. Eggs oval, 22 to 24 » long by 12 to 14 p» wide. Host.—Pelecanus occidentalis occidentalis. Location.—Small intestine. Type locality —Levantade Keys, Samana Bay, Dominican Republic. Type specimen—U.S.N.M. Helm. Coll. no. 8699; paratypes no. 8700. Galactosomum johnson differs from G. darbyi in the position of the seminal receptacle and in the shape and size of the eggs. In the former species the seminal receptacle is preovarial and the eggs are 34 to 36 w long and asymmetrical, whereas in the latter species the seminal receptacle is postovarial and the eggs are 22 to 24 » long and symmetrical. The shape of the eggs and the position of the seminal receptacle also serve to distinguish G. johnsoni from other species of the genus. G. darbyi may be distinguished from the other species of Galactosomum, viz, G. lacteum (Jagerskidld), G. erinaceum ( Poir- ier), G. cochleariforme (Rudolphi), G. cochlear (Diesing), G. semi- fuscum (Olsson), G. spinetum (Braun), G. aharoni (Witenberg), and G. baylisi (Nazmi), in the position of the genital aperture, which is near the intestinal bifurcation in G. darbyi and much farther pos- terior in the other species. There are also other differences, but these will not be discussed in this paper. A comparison of the species of Galactosomum described in this paper with Stictodora sawakinensis, a species described from Larus sp. in Egypt by Looss (1899) and reported from dogs and cats in Palestine, also from Puffinus kiihli from Suez by Witenberg (1929), shows such close relationships that it appears doubtful whether Stic- todora should be retained as a valid genus.

Ovary transversely oval, about 18 » long by 22 » wide, pretesticular and to right of acetabulum. Vitellaria posttesticular, situated dorsal to uterine coils and consisting of two groups of five to six follicles each. Uterus postacetabular and largely posttesticular.

Coll. no. 8703; paratypes no. 8704. This is the smallest species of the genus and perhaps the smallest known trematode. It resembles Levinseniella claviforme (Brandes) as described by Nicoll (1909) more than any other member of the genus, but may be distinguished from that species by its almost triangular shape, absence of prepharynx, shorter esophagus, longer intestinal ceca, and fewer eggs.

QI The first of the species of Prohemistomum, P. fajardensis, de- scribed here may be distinguished from all other species of the genus by the size of the eggs, which are only about half as large as those of the other species. The second species, P. appendiculatoides, ap- pears to be closely related to P. appendiculata, which was described by Ciurea (1916) from dogs and cats in Rumania; it differs, however, from that species in having a distinct esophagus (almost absent in P. appendiculata) and in having an acetabulum only about one half the size of the oral sucker (suckers about equal in size in P. appen- diculata). P. fajardensis also resembles in some respects a species, P. serpentum, described from a snake, Natrix piscator, by Gogate (1932) at Rangoon, India. Aside from the difference in host relation- ship, the two species may be distinguished by the fact that P. fayarden- sis is much smaller than P. serpentum, and that in the former the adhesive organ does not cover the vitellaria as it does in the latter species.

PRICE Zoological Division, Bureau of Animal Industry, U.S. Department of Agriculture (Wire ONE PLaTeE) This paper contains descriptions of five digenetic trematodes that are regarded as new. These trematodes were collected by the writer from fishes taken during the months of February and March, 1933, in the vicinity of Puerto Rico, by the Johnson-Smithsonian Deep-Sea Expedition. Inasmuch as the descriptions of these flukes are pre- liminary in nature, no attempt has been made in most instances to differentiate them from all of the species in the genera to which they have been allocated, but only from those to which they are most closely related. A more complete discussion of these forms and their relationships will be given in a later paper. The writer is indebted to Dr. George S. Myers, assistant curator of fishes, United States National Museum, for the determinations of the fish hosts. The fishes referred to as hosts without a specific name are apparently new and will be described by Dr. Myers in the near future. Family FELLODISTOMIDAE Subfamily FELLODISTOMINAE STERINGOTREMA OVATA, n. sp. Plate 1, fig. 1 Description.—Body oval, 500 » long by 300 » wide, flat and trans- parent. Cuticula very delicate, without spines. Oral sucker sub- terminal, 140 » in diameter ; acetabulum weakly muscular, 50 » long by 68 » wide, slightly preequatorial. Prepharynx absent; pharynx 40 » long by 36 w wide; esophagus apparently absent ; intestinal ceca relatively wide, éxtending to about 120 » from posterior end of body. Excretory aperture terminal; excretory vesicle almost V-shaped, its branches extending to near level of pharynx. Genital aperture at SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 91, No. 7 to SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI posterior end of pharynx, slightly to right of median line. Cirrus pouch piriform, 120 » long by 52 » wide at base, containing a short cirrus, pars prostatica and a large, globular seminal vesicle. Testes globular, about 40 » in diameter, with zones coinciding and fields separate, intercecal, postequatorial. Ovary about 4o » long by 28 p wide, to left of, and partly in zone of, acetabulum. Seminal re- ceptacle and Laurer’s canal not observed. Mehlis’ gland median, im- mediately postacetabular. Vitellaria extracecal, consisting of few, rela- tively large follicles situated largely in same zone as acetabulum and ovary. Uterus largely posttesticular, with two antero-laterally directed loops on each side which extend into extracecal fields. I-ggs oval, 24 p long by 16 p» wide. Host.—O pisthonema oglinum (Le Seur) (J-S 356). Location.—Pyloric ceca. Locality —Fajardo Roads, near Fajardo, Puerto Rico. Type specimen.—U.S.N.M. Helm. Coll. no. 8712 This species belongs in the family Fellodistomidae, subfamily Fello- distominae, and has been placed in the genus Steringotrema despite a number of differences that may ultimately necessitate the erection of a new genus for its reception. In view of the fact that only a single specimen was available for study, the writer does not feel justified in proposing a new genus for this form at this time. S/eringotrema ovata may be distinguished from all other species of the genus in having an oral sucker that is distinctly larger than the acetabulum, the oral sucker being much smaller than the acetabulum in all other species. PYCNADENA PIRIFORME, n. sp. Plate. 2 Description.—Body piriform, 629 » long and 420 p wide. Cuticula without spines. Oral sucker 140 » long by 120 » wide; acetabulum 224 pw long by 268 » wide, aperture 100 p long by 160 » wide. Pre- pharynx very short ; phary nx 80 » long by 64 p wide ; esophagus veuy short ; intestinal ceca’ relatively wide, extending to level of posterior margins of testes. ‘Genital aperture near left margin of body, at. level of anterior end of’ phary nx, Cirrus pouch slender, 168 p long by 48 » wide at base. Testes more or less globular, about 80 pin diameter, with zones coinciding and fields partially overlapping, near posterior end of body. Ovary globular, about 70 » in diameter, median, in samé zone and fields as testes. Seminal receptacle’ small, piriform, to right of vitelline reservoir. Vitellaria largely extracecal, NOR >7 NEW DIGENETIC TREMATODES—PRICE 3 extending from anterior margin of acetabulum to near ends of in- testinal ceca, the follicles more numerous in acetabular zone; vitel- line reservoir large, median, anterior to ovary. Uterus simple ; no eggs present in available material. Host.—Monocanthus hispidus (Linn.) (J-S 443). Location.—Intestine. Locality —Station 82 (lat. 18°32’48” N., long. 65°23'45” W.). Type specimen—vU.S.N.M. Helm. Coll. no. 8713. Pycnadena piriforme differs from P. lata (Linton) in having the acetabulum more anterior and the genital aperture more anterior and nearer the body margin; the vitellaria are less well developed than in P. lata, but as the specimen upon which P. piriforme is based 1s more immature than Linton’s specimens, the lesser development of the vitellaria may be only apparent. The genus Pycnadena Linton (syn., Didymorchis Linton) has been included with Fellodistomum Stafford, Steringophorus Odhner, Rho- dotrema Odhner, Steringotrema Odhner, Bacciger Nicoll, and Lin- tonium Stunkard and Nigrelli (=Gastris Luhe) in the subfamily Fellodistominae by Stunkard and Nigrelli (1930). The writer doubts whether Pycnadena should be included in this subfamily, or even in the family [ellodistomidae, since there are several characters in which it differs from all the other genera, these being the pretesticu- lar uterus, presence of a seminal receptacle and more profuse de- velopment of the vitellaria. However, at present it is left in the sub- family as a doubtful member until more material is available for study. Family ZOOGONIDAI Subfamily LECITHOSTAPHYLINAE LECITHOSTAPHYLUS ATHERINAE, n. sp.

Oral sucker subterminal, 152 to 160 » long by 100 to 133 » wide; acetabulum 80 to 100 » long by 108 to 120 p wide, 425 to 510 » from anterior end of body. Prepharynx 20 to 40 p long; pharynx 80 to 88 » long by 60 » wide; esophagus very short or absent; intestinal ceca relatively wide, extending to, or slightly beyond, level of posterior poles of testes. Genital aperture pre- acetabular, 320 to 400 » from anterior end of body, to left of median 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI line. Cirrus pouch piriform, 120 to 160 » long by 60 to 80 » wide, containing a short cirrus, a somewhat twisted seminal vesicle and numerous prostate cells. Testes lobulated, 120 to 160 » long by 60 to 80 » wide, with zones coinciding and fields separate, situated about one third of body length from posterior end. Ovary median, lobu- lated, 60 to 120 w long by 88 to 120 » wide, immediately posterior to acetabulum. Seminal receptacle globular, about 60 p» in diameter, postero-lateral of ovary. Vitellaria largely extracecal, extending from posterior margin of acetabulum to level of anterior poles of testes. Uterus long and convoluted, filling greater part of posttesticular space and entire intercecal field as far forward as ovary. Eggs 32 p long by 18 p wide. Host.—Atherina araea Jordan and Gilbert (J-S 334). Location.—Intestine. Locality—Samana Bay, near Santa Barbara de Samana, Domin- ican Republic. Type specimen—vU.S.N.M. Helm. Coll. no. 8714; paratypes no. 8715. Lecithostaphylus atherinae differs trom L. retroflexus (Molin) as described by Odhner (1911) in body shape, position of genital aper- ture, and the size of the eggs. L. retroflexa is elongate oval, the genital aperture is at the level of the pharynx, and the eggs are 41 p long by 20 » wide, whereas in L. atherinae the body possesses shoulderlike projections at the level of the ovary, which gives to it somewhat the shape of a spearhead, the genital aperture is about midway between the acetabulum and pharynx, and the eggs are 32 u long by 18 » wide. The subfamily Lecithostaphylinae contains, ac- cording to Fuhrmann (1928), the genera Lecithostaphylus Odhner, Proctophantastes Odhner, and Lepidophyllum Odhner. Manter (1926) has included in this subfamily the genus Steganoderma Staf- ford. Fuhrmann (1928) included Steganoderma in the subfamily Zoogoninae, but his action in this case probably was unintentional, since Steganoderma is obviously more closely related to the genera included in the Lecithostaphylinae than to those of the Zoogoninae. In reviewing the family Zoogonidae, which action was necessary in connection with the identification of L. atherinae, the writer has examined the types of the genera proposed by Linton (1910) and finds that Deretrema fusillus Linton is congeneric with Proctophan- tastes abyssorum Odhner and, according to priority, the genus Proc- tophantastes must fall as a synonym of Deretrema, P. abyssorum Odhner becoming D. abyssorum (Odhner). Furthermore, this re- view has shown that the genus Diplangus Linton (1910), also belongs ——_— =. NOs NEW DIGENETIC TREMATODES—PRICE on in the subfamily Lecithostaphylinae. It is possible that Mesolecitha Linton (syn., Mesorchis Linton) may belong to this subfamily, but more study is necessary before this can be determined with certainty. Family ALLOCREADIIDAE Subfamily ALLOCREADIINAE PLAGIOPORUS FUSIFORMIS, n. sp. Plate 1, fig. 4 Description.—Body fusiform, 1.27 to 1.7 mm long by 475 to 680 p wide at level of acetabulum, slightly flattened dorso-ventrally. Cuti- cula delicate, unarmed. Oral sucker 120 to 152 m in diameter ; acetab- ulum 220 to 340 p long by 280 to 576 » wide, in equatorial zone. Prepharynx 20 to 40 » long; pharynx 40 to 60 » long by 40 to 80 p wide ; esophagus 200 to 240 yp long; intestinal ceca simple, extending to level of posterior testis. Excretory aperture terminal; excretory vesicle tubular, extending anteriorly as far as level of anterior testis. Genital aperture near left margin of body and about midway between pharynx and intestinal bifurcation. Cirrus pouch slender, about 300 pu long, its base lying in median line dorsal to acetabulum, and con- taining a slender unarmed cirrus, prostate cells, and a slender, somewhat convoluted seminal vesicle; a distinct pars prostatica ap- parently absent. Testes elongated transversely, tandem and in con- tact, in anterior part of posterior third of body; anterior testis about 80 » long by 240 » wide; posterior testis 120 » long by 240 p wide. Ovary trilobed, about 60 » long by 180 p» wide, pretesticular, mostly to right of median line. Seminal receptacle and Laurer’s canal present, the latter opening in the mid-dorsal line at level of ovary. Vitellaria extending from level of genital aperture to about half way between posterior testis and posterior end of body. Uterus with relatively few coils, preovarial ; metraterm extending from near center of acetab- ulum to genital aperture. Eggs oval, 70 to 72 » long by 36 » wide, with thin, yellowish shells. Host.—Eel (Xenomystax sp.) (J-S 447 and 448). Location.—Intestine. Locality.—Station 84 (lat. 18°39’ N., long. 65°17’ W.). Type specimen——U.S.N.M. Helm. Coll. no. 8716; paratypes no. 8717. Plagioporus fusiformis appears to be more closely related to P. serotinus Stafford than to any of the other species so far placed in the genus, but differs from that species in the length of the ceca which 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI in P. fusiformis extend only to the level of the posterior testis, where- as in P. serotinus they extend to the posterior end of the body. In comparing the species of the genus Plagioporus Stafford with those included in the genus Lebouria Nicoll the writer is convinced that the latter are congeneric with P. serotinus, type of Plagioporus. Stafford’s (1904) description of P. serotinus is rather meager, but all of the generic characters are clearly indicated; therefore. the writer transfers the species Lebouria aducta Nicoll, L. acerinae Pigulevsky, L. alacris (Looss), L. coopert Hunter and Bangham, L. crassigula Linton, L. elongata Goto and Ozaki, L. idonea Nicoll, L. tsaitschikowti Layman, L. micolli \saitschikov, L. obducta Nicoll, L. tumidulum (Rudolphi), and L. varia Nicoll to the genus Plagioporus, the new combinations being, respectively, P. aducta (Nicoll), P. acerinae ( Pigulevsky ), P. alacris (Looss), P. coopert (Hunter and Bangham), P. crassigula (Linton), P. elongata (Goto and Ozaki), P. idonea (Nicoll), P. tsaitschikowi (Layman), P. nicolli (Isaitschikov), P. obducta (Nicoll), P. tumidulum (Rudolphi), and P. varia ( Nicoll). From the above species, which up to the present time have been included in the genus Lebouria, Plagioporus fusiformis may be dis- tinguished by the distinctly fusiform shape of the body and by the very large, equatorially placed acetabulum. In the extent of the in- testinal ceca posteriorly, this form resembles P. nicolli and P. cooperi more than the others; P. fusiformis may be differentiated from P. nicolli in that loops of the uterus pass between the ovary and testes in the latter species, a condition not occurring in P. fusiformis or in any of the other species of the genus. P. fusiformis differs from P. cooperi in having a larger and more equatorially placed acetabulum, in having the genital aperture situated more anteriorly and nearer the body margin, and in having the testes tandem in position instead of being placed diagonally as in P. cooper. PODOCOTYLE LANCEOLATA, n. sp. Plate 1, fig. 5 Description.—Lody lanceolate, 1.95 to 2 mm long by 645 to 850 p wide, strongly flattened dorso-ventrally and more attenuated anteri- orly than posteriorly. Cuticula without spines or ridges. Oral sucker subterminal, 100 to 189 p» in diameter; acetabulum 220 to 240 p long by 240 to 280 » wide, about one third body length from anterior end. Prepharynx short; pharynx somewhat globular, 88 to 100 p» long by 88 » wide; esophagus 160 to 200 mw long; intestinal ceca NO. 7 NEW DIGENETIC TREMATODES—PRICE 7, simple, extending to near posterior end of body. Genital aperture sinistral, cephalad of intestinal bifurcation, and about midway be- tween margin of body and esophagus. Cirrus pouch about 400 long by 100 to 120 » wide, extending to, or only slightly beyond, posterior margin of acetabulum. Testes lobed, tandem, sometimes touching, postequatorial; anterior testis 160 » long by 260 to 280 p wide ; posterior testis 160 to 180 » long by 260 to 320 » wide. Ovary trilobed, 140 » long by 240 to 320 p wide, pretesticular, and mostly to right of median line. Vitellaria well developed, extending from slightly in front of anterior margin of acetabulum to near posterior end of body. Uterus in intercecal field between ovary and acetabulum, relatively long and with several loops containing numerous eggs. Eggs oval, 56 » long by 30 p wide. Host.—Polymixia sp. (J-S 595). Location.—Intestine. Locality Station 100 (Jat. 18°40'15” N., long. 64°50’15” W.). Type specimen—U.S.N.M. Helm. Coll. no. 8719; paratypes no. 8720. Podocotyle lanceolata differs from all species of the genus except P: levinseni Isaitschikov, P. odhneri Isaitschikov, P. sygnathi Nicoll, and P. pennelli Leiper and Atkinson in that the cirrus pouch does not extend posterior to the acetabulum. Of the species mentioned above, P. lanceolata resembles P. odhneri perhaps more closely than it does any of the other species, but it may be distinguished from that form in having distinctly lobed testes, a relatively larger ovary, and more profusely developed vitellaria. P. lanceolata has a smaller ovary and a more laterally placed genital aperture, which serve to distinguish it from P. levinseni. It may be differentiated from P. sygnathi by the position and character of the testes and the extent of the vitellaria anteriorly, the testes being smooth and well separated, and the vitel- laria not extending to the acetabulum in P. sygnathi, while the testes are lobed and close together, and the vitellaria extend anterior to the acetabulum in P. lanceolata. This species may be distinguished from P. pennelli in the position of the genital aperture and in the length of the intestinal ceca, the genital aperture being situated at the level of the pharynx and the intestinal ceca extending only as far as the level of the posterior margin of the posterior testis, while the genital aperture is situated some distance posterior to the pharynx and the intestinal ceca extend to near the posterior end of the body in P. lanceolata. 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.

A. Johnson Fund NEW POLYCHAETOUS ANNELIDS By AARON L. TREADWELL Professor of Zoology, Vassar College (WitH Two Plates) The polychaetous annelids obtained by the First Johnson-Smith- sonian Deep-Sea Expedition have been submitted to me for report, and in the collection I have found a number of new species, which are here described and figured. MELAENIS Malmgren MELAENIS TROPICUS, n. sp. Plate 1, figs. 1-6 A single specimen 33 mm long and g mm wide in the greatest diameter. Twelve pairs of elytra completely cover the body. The prostomium is about I mm in diameter and carries the cirrophores of the three tentacles from which the styles have been broken. The median cirrophore overlaps the lateral ones. The prostomium (fig. 1) is rounded in outline, its transverse diameter being a trifle greater than its antero-posterior. No eyes are visible. The palps are very long and not very stout. The first parapodia are small and largely concealed by the bases of the palps. The basal portion of each parapodium narrows distally, and on its anterior border are numerous papillae (fig. 2). Terminally, there is a considerable widening, the main axis continuing into a point, from which the acicula protrudes. On the dorso-lateral sur- faces are the cirrophores for the tentacular cirri from which the styles are lost. Antero-laterally there are three tufts of setae radiating in fan shape in each tuft. The second parapodium is also small, its notopodium (fig. 3) rather broad at the base and continuing with the same diameter about half way to the apex, where it narrows asymmetrically and rapidly toa sharp point. A large acicula protrudes from the apex. Antero-dorsally, there is a tuft of setae. Small, rounded vesicles are attached to the body wall between the two parts SMITHSONIAN MISCELLANEOUS COLLECTIONS, VOL. 91, No.8 2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI of the parapodium. The neuropodium is irregularly ringed at the base and narrows at a rather uniform rate to the apex. The bending of the tip and breaking of the acicula is obviously an accident. A slender ventral cirrus extends beyond the end of the setal portion. Beginning with the third, the parapodia are very large, and the large setae of the third parapodium extends as far as the tips of the palps. In a parapodium from the middle of the body, the notopodium is short and thick but narrows abruptly to an acute tip, from which the acicula protrudes. The neuropodium is slender, longer than the notopodium, and almost circular in cross-section, ending in a blunt point. Just proximal to the end are two blunt lobes, and nearer the body is a third. From each of these protrudes a stout seta. The dorsal cirrus is very long and slender, but the ventral one hardly reaches the end of the setal lobe. The elytra are large, entirely covering the dorsal surface of the body, and most of them, if not all, overlap in the dorsal midline. They are broadly oval in outline, with the elytrophore attachment nearer one end, the long axis of the elytron being at right angles to that of the body. The elytra are thin, with entire margins and no sur- face markings. They are mostly translucent, this character being most marked near the margins, for whitish deposits occur near the elytro- phore attachment and extend for some distance outward. In a parapodium from near the middle of the body, the most noticeable setae are those of the notopodium, which curve upward and outward. The largest of these are very heavy and terminate in a point, which has barbs on either side of the end of the shaft (fig. 5). These did not appear in all somites, but this was probably due to accidental causes. The remainder of the dorsal tuft is composed of slightly smaller setae than the above, which end in sharp points and are faintly bilimbate toward the ends. On the surface of their shafts are minute points, giving it a shagreen appearance. A tuft of slender, colorless, sharp-pointed setae lies on the antero-posterior face of the notopodium. The neuropodial setae are very few and heavy (fig. 6). Toward the ends they bend slightly and taper to an acute tip, which carries two or three stout teeth on the outer surface. In the neuropodium is a tuft of setae that have sharp lateral teeth along the shaft (fig. 4). Type.—vU.S.N.M. no. 20031, collected at station Io in the Virgin Islands at latitude 18°40'30” N., longitude 64°50’ W.—latitude 18° 45'40” N., longitude 64°48’ W., in 300 fathoms. no. 8 NEW POLYCHAETOUS ANNELIDS—TREADWELL S EUPHOLOE McIntosh EUPHOLOE ACUMINATA, n. sp. Plate 1, figs. 7, 8 Only incomplete specimens are present. The type measures 28 mm for the first 50 somites and has a width anteriorly of 6 mm. The head width is 5 mm. This width continues for about the first 10 mm of body length, but behind this there is a decided narrowing. The prostomium (fig. 7) is oval in outline, with the tentacle arising in the middle of its anterior border. Dorsally there are two very in- distinct eyes (not shown in the figure), and two others, much more distinct, lie near the ventral surface. The cirrophore of the tentacle is globular and about half as long as the prostomium, but is very thin-walled. Toward the end there is a constriction, so that the style is carried on the end of a very small globular portion. The style is slender and four or five times as long as the prostomium. The first parapodia are elongated cones, truncated near the ends, and each has a very slender dorsal cirrus near its end (fig. 7). The two parapodia are in contact at their bases and on either side press tightly against the tentacle, each long, slender dorsal cirrus reaching to the end of the tentacle. This arrangement of tentacle and parapodia gives a pointed appearance to the anterior end of the animal. In each parapodium is a dense tuft of setae, which overlap from the two sides and surround the ends of tentacle and cirri. The palps are long and slender, extending beyond the tips of the first parapodial setae. The first pair of elytra carried on the first parapodium are borne on transversely oval elytrophores (fig. 7) and completely cover the prostomium. Between the elytrophores the anterior margin of the first somite protrudes over the prostomium. In one specimen this protrusion is a blunt cone; in the other it has two rounded lobes on its margin. The lower lip is prominent, its surface thrown into longitudinal folds. As stated, the first pair of elytra overlap. I am uncertain about the second, but behind this there is a definite area of the dorsal sur- face that is uncovered. Even when elytra have been removed, this clearly shows because of a dusting of fine sand grains on portions of the dorsal surface that had been uncovered by elytra. A similar covering of sand grains appears on the elytra, these grains being coarser on anterior somites. Except where overlapped by other elytra, each elytron carries a row of fine cirri around its margin, and on its outer half there are a considerable number of these on the surface. Except at the point of attachment, each elytron is very thin 4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI and soft. I am uncertain whether the denser appearance at the elytro- phore is due to a thickening of the tissue or to a greater accumulation of sand grains at that point. As far as about somite 25 the dorsal exposed portion of the body wall seems to be thin and delicate. Behind this point the body narrows, the sand grains are larger, and the elytra cover more of the surface. The last somites present in the fragments are completely covered. Beyond about somite 25 each has on its dorsal surface three transversely arranged bunches of sand grains, successive somites thus showing three longitudinal rows of sand piles. It is possible that these represent three rows of rudimentary gills, but I was unable to discover any trace of gills in them. The dorsal appearance of the first parapodium has been given above. On the ventral surface there is a short cirrus near the end of the neuropodium. The setae of this parapodium are of varying sizes but are all essentially the same in structure in that they carry two rows of toothed plates, giving the setae a double saw-tooth effect. The second parapodium carries a whorl of very fine setae, which have minute lateral plates forming spines as in the first. In the neuropodium are a few much larger setae, which are smooth throughout the greater part of their length but toward the end acquire lateral plates. Toward their ends, they widen and then narrow again, forming what one would expect to be a narrow lanceolate apex, but this suddenly ends and forms the basis for a slender and much curved terminal joint (fig. 8). The second parapodium has the form of a truncated cone, is very much annulated on its surface, and has a long cirrus at its apex, together with a bunch of smaller cirri. Except for the absence of the long terminal cirrus, the third parapodium is much like the second. The dorsal setae are like those in the noto- podium of the second parapodium, whereas ventral ones are compound but without the lateral teeth. These are continued in later somites, but the terminal joint may be very short. In the third parapodia are ‘ also very slender colorless compound setae having long and slender terminal joints.

Plate 1, figs. 9-12; plate 2, figs. 13-16 A number of specimens are in the collection, but none is entire. Anterior portions containing about 60 somites are 50 mm long. The prostomium is I mm in diameter, but if the parapodia which extend along the sides of the prostomium are measured, the total head width is 3 mm. The greatest body width is 4 mm. The prostomium (fig. 9) is oval in outline its width being about twice its length. No eyes are to be seen, but the dorsal surface is irregularly blotched with purplish patches. The tentacle is very short and slender and is inserted a little back from the anterior prostomial border. The palps are long and slender and not noticeably thickened at the bases. There are no lateral tentacles or tentacular cirri. The first parapodium (fig. 10) on either side extends forward and, together with the buccal membrane and the bases of the palps, forms the outer boundary of a space lateral to the prostomium. It was very difficult to get a satisfactory dissection of this parapodium, and the drawing is not complete. The setal portion is blunt-ended, and there is a single acicula. From the outer dorsal surface arises a tuft of very slender setae, and on the dorsal surface are numerous cirri of various sizes. No attempt has been made to draw them all, as so great a number would confuse the drawing. One as drawn is much larger than the others and may be the dorsal cirrus ; but if so, it is broken, for in another specimen (fig. 11) this cirrus is long and slender. There is a slender ventral cirrus. The second parapodium (fig. 12), 1s very thick and heavy and extends forward so as to overlap the first, the inner face of the second being slightly concave. Each carries dorsally a small, nearly circular elytra. There is no marginal indentation between the neuropodium and notopodium, and each portion carries an acicula. In the neuropodium is a bunch of very heavy setae, most of which have been broken off at about the level of the body surface. The only notopodial setae are a tuft of slender ones arising at the anterior margin of the elytrophore. A tangle of cirri similar to those of the first parapodium arise from this same position. The ventral cirrus is short and heavy. The second parapodium is larger than the first, and this increase in size continues as far as the eighth. A parapodium from near the middle of the body (fig. 13), is elongated, and the vertical diameter of its setal portion is much less than that of the body. The neuropodium widens slightly toward the end, where there are a large posterior and two smaller anterior lobes. 6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI The notopodium is smaller than the neuropodium and is more uniform in diameter throughout. Its apex is conical, but dorsal to this is a small lobe, and numerous cirri arise from the ends of both parts. In all somites a heavy gill is attached to the body wall above the para- podium. In somites having elytra this is just ventral to the cirrophore (fig. 13). In other somites the dorsal cirrus is a fleshy lobe resembling a cirrophore but lacking a style (fig. 12). The anterior elytra are very small, but later ones increase in size so that they overlap on the dorsal surface. Behind the twentieth they are lost in the specimens at hand, but apparently the large size is continued to the posterior end of the body. They are located on somites 2, 4, 5, 7, and on alternate somites behind this. All are roughly oval in outline and have smooth margins and a very deli- cate translucent appearance. A prominent feature is a brown spot near the elytrophore. The setae of the first parapodium are all very slender and long, some having smooth margins, others finely serrate. In the second parapodium the notopodial setae are like those of the first, but neuro- podial ones are shorter and heavier and curve to fine points, the terminal part being camerated (fig. 14): In later parapodia there are several kinds of setae, some like those in the second, others long, slender, and sharp-pointed, distinctly bent and carrying two rows of toothed plates (fig. 15). In the neuropodium there is a ventral bundle of compound setae, whose terminal joints are straight, pointed, and camerated (fig. 16). Type.—U.S.N.M. no. 20033, collected at station 14 at latitude 18°31’ N., longitude 66°4’10” W.—latitude 18°30'30” N., longitude 66°3/15” W., north of Puerto Rico, at 200-240 fathoms. Others were collected at station 23, latitude 18°32’15” N., longitude 66°17'45” W.— latitude 18°32’ N., longitude 66°21'15” W., north of Puerto Rico, in 260 fathoms. HYALINOECIA Malmgren HYALINOECIA BRANCHIATA, n. sp. Plate 2, figs. 17-19 This name is provisionally given to a single incomplete specimen 15 mm long and 2 mm wide, and retaining only 20 somites. Because of the lack of nuchal cirri, it belongs in the genus Hyalinoecia. The specific name refers to the unusual amount of gill development. The prostomium (fig. 17) has a width of about twice its length and carries short tentacles that are obscurely, if at all, ringed on the cirrophores and have slender styles. The style of the median no. 8 NEW POLYCHAETOUS ANNELIDS—TREADWELL 7. tentacle is lost ; those of the inner paired extend to somite Io, whereas those of the outer paired are hardly more than one-fourth as long as these. The frontal tentacles are broadly oval in outline, their bases being in contact. The palps are large and extend down over the mouth. On its anterior margin somite 1 is wider than the prostomium, and this width reappears on the posterior margin. In the middle, where the parapodia arise, it is very much wider than this, and the parapodia extend almost to the anterior prostomial border. Each parapodium carries a slender dorsal and a much heavier ventral cirrus, the latter having a heavy basal section and a slender terminal one, the two being of about equal length. Apparently there are three subequal terminal parapodial lobes, but owing to imperfect preservation, it is not possible to be certain. Each parapodium carries three stout hooked setae. Somite 2 is a trifle wider than somite 1 and less than one third as long, its anterior border being a trifle wider than its posterior. The parapodia extend forward but to a much less extent than in somite 1. Somite 3 assumes a form characteristic of the remainder of the body. Its width is about four times its length, and the lateral margins are uniformly rounded except where they extend out into the bases of the parapodia. In somite 3 the dorsal cirrus is prominent, four or more times as long as the setal lobe. The ventral cirrus is also prominent, but stouter than the dorsal. The fourth, fifth, sixth, and seventh parapodia have large dorsal and ventral cirri, the dorsal being longer than the ventral. After the seventh there is a diminu- tion in length of the cirri, and in later somites, although they are longer than the setal lobes, they are very slender. Gills are composed of several filaments, and on the sixteenth parapodium there are six of them, palmately arranged (fig. 18). Just dorsal to the insertion of the ventral cirrus, each parapodium carries a tuft of heavy setae and two aciculae. The aciculae are bluntly rounded and end just inside the surface. The setae are of two kinds: heavy ones having stout terminal and subterminal teeth covered by a hood (fig. 19), and slender bilimbate ones reaching as far as the end of the dorsal cirrus. The hooks of the first parapodium are very heavy and have a terminal and a much smaller subterminal tooth. Since only one specimen appeared in the collection, I did not think it wise to mutilate it by removing the jaws for study and I have no information concerning them. In the gill character this species seems 8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. QI rather distinctive. Verrill’s* account of H. artifex states that gills first appear on about the twenty-eighth somite and are never of more than one filament.

ALCIOPA Audouin and Milne Edwards ALCIOPA MUTILATA, n. sp. Plate 2, figs. 20, 21 This species name is provisionally suggested for a fragment of an Alciopa retaining only a limited portion of the anterior body region. Its total length is 7 mm and width at the eyes 1.5 mm. The eyes are very large and almost in contact dorsally, their lenses point- ing downward and outward so as not to be visible from a dorsal view. Ventrally, they are more widely separated (fig. 20). The median tentacle (fig. 20) is very short and inconspicuous and is located well forward between the eyes. All frontal tentacles are thick, the dorsal pair being a trifle smaller than the ventral ones. Between the dorsal frontal and the median tentacles is a pair of fleshy lips. The anterior face of the first somite is in contact with the eyes but does not enclose them in a cup effect, as it does in other species. The parapodia are conical in outline, and a single acicula protrudes at the apex (fig. 21). Only a very few setae are present, most of them having been broken. Those that remain have sharp-pointed ends, and this undoubtedly holds for all.

The posterior margin is prominent and is continued forward on either side nearly to the middle of the plate. Between these two portions is a thin membrane drawn out on the right side into three, and on the left into four, sharp-pointed processes. The surface of the cephalic plate is deeply hollowed just in front of the posterior margin and more shallow elsewhere. The median ridge extends only about half the length of the plate and has a cone-shaped outline. Its dorsal surface is marked by transverse lines. A prominent collar on the anterior margin of the first setigerous somite overlaps the posterior margin of the buccal somite for its entire circumference. The anal funnel (fig. 23), has a prominent bilobed dorsal and a single ventral lip. On the margin of the dorsal lip are a few slender cirri. The first four setigerous somites are short, the next five longer, and the final ones shorter again. There are two kinds of setae. The first are slender and sharp- pointed, arranged in tufts in which there is great variation as to length. Some are very short, others several times as long. Some at least, and probably all, are narrowly bilimbate. Toward the ends, they narrow rapidly to fine points. The hooks (fig. 24) have very long shafts, enlarged to form a collar at the point where they pro- trude from the. body surface. The distal end is bent to form a “ head,” which on the lower surface carries a large tooth. Above this is a much smaller tooth and above this several denticulations. A long tuft of subrostral hairs extends beyond the large tooth.

MYERS Assistant Curator, Division of Fishes, U.S. National Museum (WitH ONE PLatTeE) Preliminary examination of the fishes obtained by the Johnson- Smithsonian Deep-Sea Expedition in 1933 has disclosed the presence of several new forms, three of which are herewith diagnosed. Family GONOSTOMATIDAE Margrethia obtusirostra was described by Jespersen and Taning* from postlarval and adolescent individuals obtained at a depth of about 150 meters in the eastern Atlantic by the Margrethe. No exact localities are given, except for the two figured specimens, in the explanation of the plate, and as for range the authors merely state, “the distribution closely coincides with that shown by Bonapartia pedaliota,” that is, Cadiz Bay and the Atlantic south of the latitude of the Azores. The description is very short, and the authors probably intended to present a more extended account later, as they did for the Mediterranean species, but this has not appeared. I find no record of the capture of additional specimens. In the collections obtained by the Caroline I find a single large Margrethia which differs distinctly from M. obtusirostra in many ways.

Anal 21, the anterior rays more elongate. Pelvic 8. Caudal (counting from above downward) 7+10+9+6. Gill-rakers on first arch long and slender, with minute asperities, 5 on upper limb and 10 on lower. Pseudobranchiae well developed. Scales mostly lost, but there appear to be about 30 scale pockets in the midside series. Teeth in jaws uniserial, conical, and sharp. On the premaxillary the teeth are rather small, but with some enlarged on the expanded part. Median part of upper jaw toothless, the first tooth on each premaxillary enlarged and directed forward and inward. Teeth of maxillary extremely close set, every fourth to sixth tooth enlarged ; all of them strongly directed forward, those of the anterior part point- ing almost straight forward. Mandibulary teeth larger than those of maxillary, close set, every seventh or eighth tooth enlarged. A single series of small conical teeth on each palatine, the first one enlarged. Two large patches of tiny pterygoid teeth in the roof of the mouth. Photophores: One preorbital (Orb) photophore directly in front of eye, embedded in the proximal end of the maxillary bone. Three opercular (Op) photophores, one along the preopercle-opercle junc- tion, one beneath the subopercle, and one directly behind the articula- tion of the mandible. No symphysial (SO) photophore. Branchi- ostegal (Br) photophores 11. Body (BO) photophores 14, arranged peculiarly. Up to the tenth they are in a straight, compact series, but the tenth, eleventh, and twelfth are displaced upward in an ascending series. The thirteenth is set directly below the twelfth (that is, in a line with the first 9) and the fourteenth follows the thirteenth directly behind. It is this disjunction of the BO series that is the most notable character of the new fish and the one from which the specific name is derived. The pelvic base barely separates the fourteenth BO photo- phore from the four pelvic (VO) ones. The supra-anal (AO) photo- phores are 14+ 3 in number, the first two slightly elevated, but not forming an arch as in MW. obtusirostra. Top of head with three bony keels. The lateral ones begin together at the supraoccipital region and run forward and outward till they merge with the orbital rim. The median crest, more rounded in cross- section than the lateral ones, begins above the pupil and runs forward to the ethmoid region. Preopercular margin sharply inclined. Pos- terior margin of operculum nearly straight, with a slight excision medi- ally. Tooth-bearing edge of each premaxillary with a strong convex expansion posteriorly. The long and uninterrupted curve of the max- illary is rather strongly convex. Lower jaw bones rather deep and very thin.

The upper profile of the snout is flat or a little concave, and the top of the head is rounded. The dorsum then rounds slightly to the dorsal origin and thence slopes gradually to the caudal peduncle. The measurements of the holotype, in millimeters, are as follows: Standard length 31, greatest depth 10, head length 9, orbit diameter 3, length lower jaw 9, length dorsal base 7.5, length anal base 10, snout 2, snout tip to dorsal origin 16, snout tip to pelvic origin 15, snout tip to anal origin 18, least depth caudal peduncle 3.5, length caudal peduncle (from anal) 4.5, longest gill-raker (at angle) 2.5, length caudal fin 10. All longitudinal measurements, save those of the lower jaw and fin bases, are made as to the verticals of the points indicated, on an ideal longitudinal axis of the fish. Entire snout and tip of lower jaw hyaline. Cheeks, opercles, and middle area of sides back to above first third of anal base iridescent bluish silvery. From above eye to end of dorsal base the back is black- ish, and there is a dark patch or bar over the origin of the caudal rays. Posterior part of body yellowish.

Family TRIACANTHIDAE The discovery of a second genus and species of this family in the Western Hemisphere by the Johnson-Smithsonian Deep-Sea Expedi- tion is exceptionally interesting. Hollardia hollardi was described by Poey in 1861 from a single specimen cast ashore near Havana. Poey’s type, a dried skin in good condition, is still the only example known, and it 1s here figured (pl. 1, fig. 2) for comparison with the new genus. The two specimens referred to H. hollardi by Breder in 1925 are considered below to belong to a distinct species. In attempting to work out the relationships of the new form, it was found useful to prepare a table of the genera, and since there has been no recent attempt at a revision, my notes are presented in the form of a key followed by brief remarks on the genera. In describing the new genus and preparing the synopsis, I have been fortunate in having at hand examples of all the described recent genera, from the col- lections of the United States National Museum. I am unable at present to correlate either of the two fossil tria- canthid genera, Acanthopleurus Agassiz* and Marosia de Beaufort * with the recent forms. Both seem near Triacanthus. 7 See Woodward, Cat. Foss. Fish. British Mus., part 4, p. 566, 1901. *Jaarb. Mijnw. Ned.-Ind., vol. 54, pt. 1, p. 142, pl. 5, fig. 5, 1926.

QI Anal fin of 13 soft rays, first and last short and slender, all of them with asperities basally similar to those of soft dorsal rays. Anal origin under base of seventh dorsal ray. Pelvic fins each of 1 strong spine, equal to first dorsal spine in length, and a tiny spine in the axil (hinged like the larger one) with its base rather heavy and its tip soft and tapering. Occasionally this tip is absent. The large spine is covered with minute asperities for nearly half its length. Distally, it is grooved like the dorsal spines. Origin of pelvic spine under base of first dorsal spine. Pelvic girdle rather wide beneath; width of girdle (inclusive of bases of the ap- pressed spines) is one half the length of the spines, whereas the same measurement enters the length of the spines two and one half times in the type of Hollardia hollardi. Pectoral fins rather short and rounded, of 14 rays, the first (upper) one very short and slender. Upper end of pectoral base below mid- depth of body at this point, opposite middle of gill opening. Pectoral rays with asperities on both sides. Longest ray slightly less than orbit diameter. Caudal fin more or less rounded, of 10 principal branched rays and t shorter undivided supporting ray above and below. Length of caudal fin equals half body depth. Teeth minute, conical, strictly in one series. There are 38 to 44 teeth in each jaw. Body rather compressed (more so in young), thick-set, widest at the head, deepest at end of spiny dorsal in the adult, and at first dorsal spine in half grown. Depth 2.17 in standard length (adult) to 1.84 (half grown). Head 2.69 (adult) to 1.84 (half grown). Eye enor- mous, twice in head. Interorbital wide, 1.4 in eye diameter. Snout blunt, 1.75 in eye. Gill opening very restricted, half above and halt below level of upper border of pectoral base, lower extremity of the slit not reaching down to level of lower part of pectoral base. Pseudo- branchiae well developed, but restricted to the upper half of the oper- cular wall. Squamation rough, resembling that of F/ollardia hollard1 but the individual scales much smaller. Lateral line not evident. Coloration in alcohol yellowish white, with a black spot about one third eye diameter on the upper part of the side under origin of soft dorsal. A color sketch from life shows the body marbled orange-pink above, pale on belly, the large spot dark brown ocellated with a narrow orange ring and a larger white ring. Dorsal spines orange-pink, fins otherwise colorless. Pupil black. Iris white. (Eriomma, from épt, an intensive particle, and ¢éupe, eye; in al- lusion to the enormous eyes and the ocellated spot.) NO. 9 NEW DEEP-WATER FISHES—MYERS N KEY TO GENERA OF TRIACANTHIDAE 1a. Front pair of teeth in each jaw wide compressed incisors, forming a beak; caudal peduncle long; mouth terminal; spinous dorsal 5; pseudobranchiae present, little developed, confined to upper part of opercular wall.
